Author is Duan, Jicheng; Wang, Yuquan; Qi, Liangliang; Guo, Peng; Pang, Xiaobo; Shu, Xing-Zhong.

Cross-electrophile C-Si coupling has emerged as a promising tool for the construction of organosilanes, but the potential of this method remains largely unexplored. Herein, we report a C(sp3)-Si coupling of unactivated alkyl bromides with vinyl chlorosilanes. The reaction proceeds under mild conditions, and it offers a new approach to alkylsilanes. Functionalities such as Grignard-sensitive groups (e.g., acid, amide, alc., ketone, and ester), acid-sensitive groups (e.g., ketal and THP protection), alkyl fluoride and chloride, aryl bromide, alkyl tosylate and mesylate, silyl ether, and amine were tolerated. Incorporation of the -Si(vinyl)R2 moiety into complex mols. and the immobilization of a glass surface by formed organosilanes were demonstrated.

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.

Two new compounds based on one mononuclear nickel(II) and one homobinuclear copper(II) complexes resp. and of general formula [Ni(dmbpy)2(CH3COO)]ClO4 (1) and [Cu2(dmbpy)2(CH3COO)3]ClO4 (2) with dmbpy = 5,5′-dimethyl-2,2′-bipyridine, were synthesized by hydrothermal treatment. Both were influenced by the coordinated acetate ion mol. The crystal and mol. structures of (1) and (2) were determined by single crystal x-ray diffraction method and both compounds were addnl. characterized by elemental and TGA, FTIR spectroscopy, powder X-ray diffraction and UV-visible. The mononuclear complex (1) shows a distorted octahedral geometry around the metal ion. However, the copper(II) compound crystallizes as an homobinuclear system, in which each of the metal ions is located into the N2O3 coordination spheres adopting a distorted square pyramidal geometry. In (2) the intramol. distance between two copper atoms is of the order of Cu1-Cu2 = 3.38(2) Å. In both crystals packing of these two complexes, H-bonding, π···π, and C-H···π interactions are operative in forming supramol. motifs. 1 Displays two 1D chains that lead to form R88(42) ring motifs, repetition of which generates a 2D supramol. network. These chains interacts with the neighboring ones via intermol. C-H···π and π···π stacking interactions, giving a 3D-stacking network (2D+1D→3D). Formation of a 2D supramol. sheet in the solid state structure of (2) is facilitated by the C-H···O, C-H···π and π···π interactions (1D+1D→2D). Hirshfeld surface anal. and theor. calculations were carried out on the two compounds C-H···O, C-H··· π and π···π stacking interactions play a paramount role in the stabilization of the supramol. architecture of (1) and (2). In addition, absorption spectra reveal their semi-conductive nature (4.19 eV for (1)·and 4.43 eV for (2)).

Author is Du, Dan-Dan; Ren, Ning; Zhang, Jian-Jun.

A family of lanthanide-based self-assembling complexes constructed from 2-fluorobenzoic acid and 5,5′-dimethyl-2,2′-bipyridine have been successfully fabricated via conventional synthesis, namely, [Ln(2-FBA)3(5,5′-DM-2,2′-bipy)]2 (2-FBA = 2-fluorobenzoate, 5,5′-DM-2,2′-bipy = 5,5′-dimethyl-2,2′-bipyridine, Ln = La (1), Pr (2), Nd (3), Sm (4), Gd (5), Dy (6), Ho (7), Er (8)). The obtained complexes are investigated by elemental anal., IR spectra, Raman spectra and single-crystal x-ray diffraction. Crystallog. results exhibit that each Ln3+ ion of them is located in a distorted Muffin coordination sphere finished by seven oxygen atoms of 2-FBA ligands and two nitrogen atoms of 5,5′-DM-2,2′-bipy ligand. Interestingly, although complexes 1-6 and 7-8 have the same formula unit, the differences in hydrogen bond interactions lead to different supramol. structures. Besides, the thermal decomposition mechanism of the complexes has been studied by TG/DSC-FTIR technol. The results show that these complexes are thermally stable up to 450 K. In addition, complexes 4 and 6 both exhibit the characteristic fluorescence of lanthanide ions, i.e., complex 4 exhibits characteristic 4G5/2→6HJ/2 (J = 5, 7, 9) transitions, and complex 6 shows characteristic 4F9/2→6HJ/2 (J = 15, 13) transitions.

Recommanded Product: 5,5′-Dimethyl-2,2′-bipyridine. 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.

A series of mononuclear DyIII compounds, [Dy(tmpd)3(4,4′-dmpy)] (1), [Dy(tffb)3(4,4′-dmpy)] (2), [Dy(tffb)3(5,5′-dmpy)] (3), and [Dy(tmpd)3(5,5′-dmpy)] () [tmpd = 4,4,4-trifluoro-1-(4-methoxyphenyl)-1,3-butanedione, tffb = 4,4,4-trifluoro-1-(4-fluorophenyl)-1,3-butanedione, 4,4′-dmpy = 4,4′-dimethyl-2,2′-bipyridyl, and 5,5′-dmpy = 5,5′-dimethyl-2,2′-bipyridyl], have been synthesized by modifying β-diketonate ligands and capping N-donor co-ligands. DyIII ions in 1-4 possess N2O6 octacoordinated environments. Compounds 1 and 2 exhibit distorted trigonal dodecahedron configurations, while 3 and 4 display distorted square antiprismatic configurations. Systematic investigations of the a.c. measurements indicate the different magnetic relaxation dynamics with energy barriers (Ueff) of 66 K (1, 45 cm-1), 189 K, (2, 131 cm-1), 115 K (3, 79 cm-1), and 205 K (4, 142 cm-1). To deeply understand their different magnetic behaviors, the magnetic anisotropies of 1-4 were studied by ab initio calculations From ab initio calculations, the energies of the first excited state (KD1) are consistent with the exptl. Ueff under zero d.c. field. Compound 4 presents the largest Ueff because of the smallest gX,Y and μqTM as well as the most strong axial crystal field parameters (CFPs) among compounds 1-4. The M vs. H data exhibit butterfly-shaped hysteresis loops at 2 K for 1-4. The different coordination geometries, the magnetic dynamics, the electrostatic repulsion, and CFPs result from the different substituent effects of ligands, including the electronic effect, the steric effect, and the positions of substituted groups.

Rhenium carbonyl complexes with substituted 2,2′-bipyridines I (2a-4a, X = Cl, R1, R2: H, H; EtOCO, Et; Fmoc, H; 2b-4b, X = Br, R1, R2: H, H; EtOCO, Et; Fmoc, H) were prepared as amino acid isosteres and resolved by chiral chromatog. An organometallic complex that mimics an amino acid, also known as an amino acid isostere, can be synthesized from a functionalized bipyridine ligand and a fac-[Re(CO)3]+ center. The reaction of an achiral ligand and metal results in a racemic mixture of chiral-at-metal complexes. These metal species have amine and carboxy termini, a side chain type unit that can be varied, as well as the chiral metal that is analogous to the α carbon of an amino acid. The racemic mixtures can be separated into enantiomers by chiral chromatog., and the metal complexes can be incorporated into peptides by using solid-phase peptide synthesis.

Quality Control of 5,5′-Dimethyl-2,2′-bipyridine. 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 H/D solvent isotope effects on the photoracemization reaction of enantiomeric the tris(2,2′-bipyridine)ruthenium(II) complex and its analogues. Author is Asahara, Masahiro; Kurimoto, Haruhiko; Nakamizu, Masato; Hattori, Shingo; Shinozaki, Kazuteru.

This work assessed solvent isotope effects on the photoracemization rate and emission lifetime for [Ru(bpy)3]2+ (bpy = 2,2′-bipyridine) in water. An anal. of the effects of temperature on photoracemization rate and emission lifetime demonstrated that the transition from one enantiomer to the other is unaffected by the isotopic composition of the solvent. Also deactivation from the metal-to-ligand charge-transfer (3MLCT) excited state to the ground state is responsible for the solvent isotope effect on the photoracemization rate. The photoracemization reaction proceeds via a bond-breaking mechanism. In this process, a five-coordinated species produced through breaking of the Ru-N bond in the 3d-d* state undergoes a structural change to produce an achiral five-coordinated species. An anal. of the effect of temperature on emission lifetime, excluding the activation to the 3d-d* state that leads to the structural change, showed that the solvent isotopic composition affects deactivation from the 4th MLCT state.
