Formula: C12H12N2. Aromatic compounds can be divided into two categories: single heterocycles and fused heterocycles. Compound: 5,5′-Dimethyl-2,2′-bipyridine, is researched, Molecular C12H12N2, CAS is 1762-34-1, about Copper-functionalized nanostructured silica-based systems: Study of the antimicrobial applications and ROS generation against gram positive and gram negative bacteria. Author is Diaz-Garcia, Diana; Ardiles, Perla R.; Diaz-Sanchez, Miguel; Mena-Palomo, Irene; del Hierro, Isabel; Prashar, Sanjiv; Rodriguez-Dieguez, Antonio; Paez, Paulina L.; Gomez-Ruiz, Santiago.

A series of copper-functionalized SBA-15 (Santa Barbara Amorphous) materials containing the ligands triethoxysilylpropylmaleamic acid (maleamic) or triethoxy-3-(2-imidazolin-1-yl)propylsilane (imidazoline) have been prepared The nanostructured silica-based systems SBA-maleamic, SBA-imidazoline, SBA-maleamic-Cu and SBA-imidazoline-Cu were characterized by several methods observing that the functionalization took place mainly inside the pores of the mesoporous system. The antimicrobial behavior of the synthesized materials against Staphylococcus aureus and Escherichia coli was tested observing a very potent activity of the copper-functionalized systems (min. inhibitory concentration (MIC) and min. bactericidal concentration (MBC) values for SBA-maleamic-Cu of ca. 31.25 μg/mL, which correspond with ca. 1.13 μg/mL of Cu). A study of the oxidative stress promoted by the synthesized materials showed that the SBA-maleamic-Cu and the SBA-imidazoline-Cu were able to increase the reactive oxygen species (ROS) production in S. aureus by 427% and 373%, resp., while this increase was slightly lower in E. coli (387 and 324%, resp.). Furthermore, an electrochem. study was carried out in order to determine if these materials interact with lysine or alanine to validate a potential antimicrobial mechanism based on the inhibition of the synthesis of the peptidoglycan of the bacterial wall. Finally, these studies were also performed to determine the potential interaction of the copper-containing materials with glutathione in order to assess if they are able to perturb the metabolism of this tripeptide.

Recommanded Product: 5,5′-Dimethyl-2,2′-bipyridine. So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic. Compound: 5,5′-Dimethyl-2,2′-bipyridine, is researched, Molecular C12H12N2, CAS is 1762-34-1, about Dehydrogenative Synthesis of 2,2′-Bipyridyls through Regioselective Pyridine Dimerization.

2,2′-Bipyridyls have been utilized as indispensable ligands in metal-catalyzed reactions. The most streamlined approach for the synthesis of 2,2′-bipyridyls is the dehydrogenative dimerization of unfunctionalized pyridine. Herein, we report on the palladium-catalyzed dehydrogenative synthesis of 2,2′-bipyridyl derivatives The Pd catalysis effectively works with an AgI salt as the oxidant in the presence of pivalic acid. A variety of pyridines regioselectively react at the C2-positions. This dimerization method is applicable for challenging substrates such as sterically hindered 3-substituted pyridines, where the pyridines regioselectively react at the C2-position. This reaction enables the concise synthesis of twisted 3,3′-disubstituted-2,2′-bipyridyls as an underdeveloped class of ligands.

Name: 5,5′-Dimethyl-2,2′-bipyridine. The mechanism of aromatic electrophilic substitution of aromatic heterocycles is consistent with that of benzene. Compound: 5,5′-Dimethyl-2,2′-bipyridine, is researched, Molecular C12H12N2, CAS is 1762-34-1, about High sensitivity and selectivity of aminoantipyrine schiff base for recognition of Fe2+. Author is Chen, Sheng-tian; Zhang, Yu; Zhao, Jian-ying; Ma, Kui-rong; Li, Rong-qing; Tang, Guo-dong.

An aminoantipyrine based chemosensor, (E)-1,5-dimethyl-4-((2-(4-methylpyridin-2-yl)pyridin-4-yl)methyleneamino)-2-phenyl-1,2-dihydropyrazol-3-one(L), derived from 4-aminoantipyrine and 2-(4-methylpyridin-2-yl) isonicotinaldehyde, was synthesized and the optical and metal sensing properties were investigated. The chemosensor L showed a selective colorimetric sensing ability for Fe2+ by changing colors from pale yellow to deep red in water-ethanol (9:1, V/V) medium, which facilitates the ‘naked-eye’ recognition of Fe2+ from other examined metal ions. The complex stoichiometry of Fe2+ to L(1:3,[FeL3]2+) was obtained by Job’s method. The association constant was determined to be 3.70×1021 L3·mol-3. The present results indicate that the chemosensor L could be used as a selective, sensitive colorimetric sensor for Fe2+.

Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. Compound: 5,5′-Dimethyl-2,2′-bipyridine, is researched, Molecular C12H12N2, CAS is 1762-34-1, about Spectroscopic, structural and DFT studies of luminescent Pt(II) and Ag(I) complexes with an asymmetric 2,2′-bipyridine chelating ligand.Product Details of 1762-34-1.

A new unsym. substituted 2,2′-bipyridine ligand, 5-methyl-5′-carbomethoxy-2,2′-bipyridine (L) was isolated from the dry distillation of the copper(II) complex, mono-aqua-bis(trans-5-methyl-pyridine-2-carboxylato-N,O)copper(II). The ligand was fully characterized. The spectroscopic and single-crystal x-ray diffraction (SCXRD) studies of the coordination compounds of the ligand with platinum(II) and silver(I); cis-Pt(L)Cl2 (1) and [Ag(L)2]PF6 (2), resp. are reported. In 1, the Pt center coordinates to tertiary N atoms of the ligand and two chloride ions to form a neutral square-planar coordination sphere, while in 2, the Ag(I) center is coordinated by two ligands through N atoms to generate a cationic flattened tetrahedron geometry in which two mean planes intersect each other at 50.93°. The pyridine rings are nearly coplanar as revealed by the torsion angle of N2-C7-C6-N1 1.32(5)°. In both complexes, L acts as a chelating ligand through pyridyl N atoms. In 1, the mol. units are stacked in a head-to-tail fashion with a Pt···Pt separation of 3.5 Å. Supramol. self-assembly of the mol. units by extensive intermol. contacts through C-H···Cl and C-H···O between the adjacent units results in an infinite two-dimensional flattened-out herringbone structure in the crystalline state. In 2, the mol. units are interconnected with each other by C-H···O contacts between the adjacent units running parallel to each other. Both complexes are fluorescent in solution and have emission maxima in the UV-Vis regions, which is a very important property for optoelectronic applications. DFT (d. functional theory) and TD-DFT (time-dependent-DFT) calculations were performed at B3LYP/6-311+G(d,p)/LANL2DZ level to explore structural, electronic, and spectroscopic properties to compare with the exptl. results. The MOs were carried out with DFT at the same level.

The reaction of [Rh(μ-Cl)(cod)]2 with diimines, differing in their steric and electronic properties, and with diphenylphosphine oxide leads to the oxidative addition products, hydrido-phosphinito-Rh(III) complexes {Rh(PPh2OH)(PPh2O)(NN)(H)Cl} (1), stabilized by the formation of a hydrogen bonded phosphinous acid-phosphinito quasi-chelate [(PO···HOP)-κ2P]. Exchange of hydride by chloride to afford {Rh(PPh2OH)(PPh2O)(NN)Cl2} (2) occurs in hydrido complexes containing low steric hindrance diimines and is inhibited for complexes containing encumbered diimines. Complexes 1 react with BF3·OEt2 with exchange of the acidic proton by BF2, and transformation of the quasi-chelating PO···HOP into a chelating PO-BF2-OP ligand in {Rh{(PPh2O)2BF2}(NN)(H)Cl} (3). The reaction of [Rh(μ-Cl)(nbd)]2 or [Rh(acac)(nbd)] with diphenylphosphine oxide leads to coordinatively unsaturated nortricyclyl-phosphinito-Rh(III) complexes, {Rh(PPh2OH)(PPh2O)(ntyl)(μ-Cl)}2 (4) or {Rh(PPh2OH)(PPh2O)(ntyl)(acac)} (6), resp. Their reaction with BF3·OEt2 results in the corresponding {Rh{(PPh2O)2BF2}(ntyl)(μ-Cl)}2 (5) or {Rh{(PPh2O)2BF2}(ntyl)(acac)} (7). Some of these new complexes have shown catalytic activity in hydrophosphinylation of alkynes, with {Rh(PPh2OH)(PPh2O)(NN)(H)Cl} containing encumbered NN being efficient and regioselective catalysts in the hydrophosphinylation of phenylacetylene with diphenylphosphine oxide to produce (E)-diphenyl(styryl)phosphine oxide.

Two novel lanthanide complexes, [Ln2(3,4-DClBA)6(5,5′-DM-2,2′-bipy)2(C2H5OH)(H2O)] (Ln = Gd (1), Tb (2)); 3,4-DClBA: 3,4-dichlorobenzoate; 5,5′-DM-2,2′-bipy: 5,5′-dimethyl-2,2′-bipyridine have been hydrothermally synthesized and structurally characterized by elemental anal., IR spectrum, thermal anal. and single x-ray diffraction techniques. The binuclear complexes 1-2 are isomorphous and crystallize in the triclinic crystal system and P1̅ space group, and each metal center is eight-coordinated with distorted square antiprismatic mol. geometry. The structure of this type of complex is unique in that the solvent ethanol mol. participates in the coordination. Complexes 1-2 are stitched together via π-π stacking interactions and hydrogen bonding interactions to form the 1D, 2D supramol. structures. The thermal decomposition mechanisms of two complexes were obtained by TG-DSC/FTIR techniques. The molar heat capacities of the complexes 1 and 2 are measured by a DSC instrument over the temperature range from 255.15 to 323.15 K and thermodn. functions were calculated by fitted polynomial and thermodn. equations.

A compound of {[Ni(5,5′-Dimethyl-2,2′-bipyridine)3](SCN)2}2(a) was synthesized and characterized by FTIR, UV-visible spectroscopy, elemental anal., luminescence and x-ray crystallog. The single crystals were obtained by slow crystallization from a methanol solution The complex is composed of nickel cation chelated by three neutral bipyridine ligands and two (SCN-) ions outside the coordination sphere. The nano form of the synthesized complex (b) was prepared by a sonochem. process and confirmed with XRD, SEM and FTIR. The average size of the particles was 37 nm from SEM. Thermodn. parameters (ΔH°, ΔS° and ΔG°) calculated from FS-DNA interaction of complexes showed that hydrogen bonding and van der Waals interactions have an essential function in the interaction of DNA-Ni(II) complex, and the interaction mode is groove binding. Viscosity measurement illustrated that relative viscosity of DNA remained unchanged with the adding concentrations of complexes. CD spectra showed that the structure of DNA was changed. The antibacterial properties were investigated in vitro against standard Gram-pos. and Gram-neg. bacterial strains. The results of antibacterial tests showed that (a) was a stronger antibacterial agent than the free ligand, and that the antibacterial effect of (b) was stronger than the one of (a). The cytotoxicity activity experiments against MCF-7, KB and A549 cells revealed low to moderate antiproliferative activity of the complex (b) against cancer cells. The mol. docking results exhibited groove mode of binding, confirming previously obtained data from spectroscopy, viscometry and CD.

SDS of cas: 1762-34-1. The reaction of aromatic heterocyclic molecules with protons is called protonation. Aromatic heterocycles are more basic than benzene due to the participation of heteroatoms. Compound: 5,5′-Dimethyl-2,2′-bipyridine, is researched, Molecular C12H12N2, CAS is 1762-34-1, about Stable Radical Cation-Containing Covalent Organic Frameworks Exhibiting Remarkable Structure-Enhanced Photothermal Conversion. Author is Mi, Zhen; Yang, Peng; Wang, Rong; Unruangsri, Junjuda; Yang, Wuli; Wang, Changchun; Guo, Jia.

The production of a radical cation-containing covalent organic framework (COF) has been accomplished by sequential in situ reactions, quaternization, and one-electron reduction of the 2,2′-bipyridine-based COFs. The acid-catalyzed COF formation enables the cis configuration of 2,2′-bipyridyl moieties in the structure, of which the stability arises from the eclipsed stacking of the two-dimensional layered structure. The postfunctionalization generates cyclic alkylated diquats as the sole products from the controlled quaternization. The reduction of diquat cations on the COF skeletons results in a large number of radical cations, which delocalize and uniaxially stack on top of one another by virtue of interlayered π-electronic couplings. The absorption of the near-IR (NIR) region exhibited by the cationic radical COF is remarkably high owing to the intercharge transfer across the π-coupling interlayers. Also, the long-range array of extended and planar frameworks in such a COF leads to the extra stability of the radical cations against external stresses. The structure-enhanced performance of the COF material is witnessed with photothermal conversion efficiencies of as high as 63.8 and 55.2% when exposed to 808 and 1064 nm lasers, resp. Further PEG modification on such a COF allows photoacoustic imaging and photothermal therapy in vivo under NIR light illumination to be manifested.

Author is Pan, Yao; Zhang, Nan; Liu, Chun-Hua; Fan, Shilu; Guo, Song; Zhang, Zhi-Ming; Zhu, Yuan-Yuan.

The merger of photocatalysis and transition-metal catalysis is of particular interest to develop useful and challenging synthetic methodologies. The catalytic activities of conventional dual-catalytic systems, however, are limited by the low synergistic efficiency between discrete catalytic centers due to their long average distance in solution Herein we carefully decorated Ir(III) photosensitizers and Ni(II) transition-metal catalyst into flexible polymers to afford two polymer-supported dual catalysts (P1-Ni and P2-Ni). These polyelectrolyte-type metallopolymers assembled into spherical polymer particles in some polar solvents. Their unique mol. and assembled structure contributed to shortening the distance between catalytic centers and increasing the local catalysts′ concentration within the catalyst, thereby greatly facilitating their electron, energy, and organic radical transfers during the catalytic cycles. The enhanced energy interaction and matched redox potential between two catalytic centers within the polymer were confirmed by steady- and transient-state luminescent spectra and cyclic voltammetry. These features enable them in catalyzing challenging organic transformations that involve efficiently incorporated photocatalytic and transition-metal catalytic cycles. We demonstrated that these two catalysts were highly effective in catalyzing C-S cross-coupling, C-O functionalized, C-N cross-coupling, and C-C cross-coupling reactions with broad substrate scopes and low catalyst loadings with turnover numbers of ~3100, ~1500, ~1400, and ~500, resp. This work provides a general methodol. to merge photosensitizer and transition-metal catalyst in a flexible polymer for significantly boosting the catalytic activity.
