New insight is provided into the chemistry of 12 para-substituted nitrobenzene compounds, using the high-level computational method G3(MP2) and DFT methods. The results show that the chemical properties of the nitrobenzene molecules, such as reduction potential, ionization energy, proton affinity, pK(a), interaction energy of the fragments, hyperpolarizability, exaltation index, band gap, UV electron excitation, and QTAIM properties, are controlled by the strong coupling between the nitro group (NO2) and the nature of the various para-substituents via the benzene ring as their conducting link. As the electron donating tendency of the para-substituent increases in the molecules, the electron cloud around the nitro group also increases, resulting in contraction of the N-C bonds and elongation of the N=O bonds, consequently leading to gradually increasing electron conductivity, polarizability, and ionization energy but lower proton affinity, thereby progressively impeding the reduction potential of the molecules. The experimental reduction potential was reproduced to a high degree of accuracy, with a mean absolute deviation (MAD) of 0.048V, depending on the computational method used and the choice of the free energy circle. Additionally, the experimental electron affinity and proton affinity of the 12 molecules were reproduced to a high degree of accuracy.

An efficient one pot strategy has been developed for the synthesis of 2-acylbenzothiazoles and quinoxalines from aryl methyl ketones. A variety of heterocycles of these two categories could be prepared in a two-step sequence in excellent yields. The reaction was performed starting from aromatic ketones via an aryl gloxal intermediate which, on further condensation with 2-aminobenzenethiol or o-phenylenediamine, produces the corresponding heterocyclic skeleton. Aromatic ketones are initially treated with TsNBr2 in DMSO at 65 degrees C for 3 h and the crude reaction mixture was treated with 2-aminobenzenethiol (at 80 degrees C) or o-phenylenediamine (at RT) to generate the final compound.

A quantitative Lewis acidity/basicity scale toward boron-centered Lewis acids has been developed based on a set of 90 experimental equilibrium constants for the reactions of triarylboranes with various O-, N-, S-, and P-centered Lewis bases in dichloromethane at 20 degrees C. Analysis with the linear free energy relationship log K-B=LA(B)+LBB allows equilibrium constants, K-B, to be calculated for any type of borane/Lewis base combination through the sum of two descriptors, one for Lewis acidity (LA(B)) and one for Lewis basicity (LBB). The resulting Lewis acidity/basicity scale is independent of fixed reference acids/bases and valid for various types of trivalent boron-centered Lewis acids. It is demonstrated that the newly developed Lewis acidity/basicity scale is easily extendable through linear relationships with quantum-chemically calculated or common physical-organic descriptors and known thermodynamic data (Delta HBF3 ). Furthermore, this experimental platform can be utilized for the rational development of borane-catalyzed reactions.

Although alkynes have been extensively exploited in [2 + 2 + 2] cycloadditions with nitriles to form N-heterocyclic aromatics, the alkyne-like metal carbon triple bond has never been used in [2 + 2 + 2] cycloadditions with nitriles. We demonstrate the synthesis of the first metallapyrazine through [2 + 2 + 2] cycloaddition reactions of a metal carbyne complex with nitriles. Experimental observations and density functional theory calculations are evidence for the aromatic character of the metallapentalenopyrazine.

Herein we report the scalable synthesis of Co/N-codoped porous carbon (Co/N-C) catalysts by pyrolyzing poly (Schiff base)/Co(II) complex. The strong Co(II)-binding affinity of poly(Schiff base) leads to the formation of uniformly distributed Co(0) nanoparticles, Co-N-x species, and N-C configurations, in which their catalytic contributions are confirmed and estimated by ligand-poisoning and acid-etching experiments and the Co-N-x species has been proved to be highly active for catalytic transfer hydrogenation (CTH) reaction. Consequently, the as-prepared Co-N/C-950 catalyst exhibits an ultrahigh activity for the CTH of 4-nitrophenol (4-NP) with a TOF of 226 mol(4-NP) mol(Co)(-1) min(-1) (13560 h(-1)) together with an excellent selectivity for CTH of challenging nitroarenes. Moreover, the Co(0) nanoparticles embedded in the Co-N/C-950 catalyst can be further transformed to Co4N phase by a facile nitridation reaction, yielding Co4N-N/C-950 catalyst with even higher activity for the CTH of 4-NP (TOF up to 310 mol(4-NP) mol(Co)(-1) min(-1)).

The reaction of LH [L = {(ArNH)(ArN)-C=N-C=(NAr)(NHAr)}; Ar =2,6-Et-2-C6H3] with a commercially available alane amine adduct (H3Al center dot NMe2Et) in toluene resulted in the formation of a conjugated bis-guanidinate (CBG)-supported aluminum dihydride complex, i.e., LAIH(2) (1), in good yield. The new complex has been thoroughly characterized by multinuclear magnetic resonance, IR, mass, and elemental analyses, including single-crystal structural studies. Further, we have demonstrated the aluminum-catalyzed hydroboration of a variety of nitriles and alkynes. Moreover, aluminum-catalyzed hydroboration is expanded to more challenging substrates such as alkene, pyridine, imine, carbodiimide, and isocyanides. More importantly, we have shown that the aluminum dihydride catalyzed both intra- and intermolecular chemoselective hydroboration of nitriles and alkynes over other reducible functionalities for the first time.

Modified polycyanostyrene and polynitrostyrene microspheres were designed and synthesized, which proved to be an effective carrier to prepare gold nanoparticles with pentazole gold as a catalyst precursor. The developed gold nanoparticles were characterized using scanning electron microscopy, transmission electron microscopy, energy dispersive X-ray, X-ray power diffraction and X-ray photoelectron spectrometry. In addition, it was observed that this catalytic system successfully achieved application in the synthesis of cinnoline derivatives and hydration reactions in high yields. Mechanism investigation was conducted to better understand these transformations and catalyst systems. To the best of our knowledge, this is the first example of utilizing pentazole gold as the catalyst precursor and achieving catalytic applications.

Enantiopure secondary alcohols are fundamental high-value synthetic building blocks. One of the most attractive ways to get access to this compound class is the catalytic hydroboration. We describe a new concept for this reaction type that allowed for exceptional catalytic turnover numbers (up to 15 400), which were increased by around 1.5-3 orders of magnitude compared to the most active catalysts previously reported. In our concept an aprotic ammonium halide moiety cooperates with an oxophilic Lewis acid within the same catalyst molecule. Control experiments reveal that both catalytic centers are essential for the observed activity. Kinetic, spectroscopic and computational studies show that the hydride transfer is rate limiting and proceeds via a concerted mechanism, in which hydride at Boron is continuously displaced by iodide, reminiscent to an S(N)2 reaction. The catalyst, which is accessible in high yields in few steps, was found to be stable during catalysis, readily recyclable and could be reused 10 times still efficiently working.

In this study, a series of 20 chalcone derivatives was synthesized, and their antiproliferative activity was tested against the human T cell acute lymphoblastic leukemia-derived cell line, CCRF-CEM. On the basis of the structural features of the most active compounds, a new library of chalcone derivatives, according to the structure-activity relationship design, was synthesized, and their antiproliferative activity was tested against the same cancer cell line. Furthermore, four of these derivatives (compounds 3, 4, 8, 28), based on lower IC50 values (between 6.1 and 8.9 mu M), were selected for further investigation regarding the modulation of the protein expression of RACK1 (receptor for activated C kinase), protein kinase C (PKC)alpha and PKC beta, and their action on the cell cycle level. The cell cycle analysis indicated a block in the G0/G1 phase for all four compounds, with a statistically significant decrease in the percentage of cells in the S phase, with no indication of apoptosis (sub-G0/G1 phase). Compounds 4 and 8 showed a statistically significant reduction in the expression of PKC alpha and an increase in PKC beta, which together with the demonstration of an antiproliferative role of PKC beta, as assessed by treating cells with a selective PKC beta activator, indicated that the observed antiproliferative effect is likely to be mediated through PKC beta induction.
