A novel palladium(0)-catalyzed intermolecular coupling reaction of 2-gem-dibromovinylanilines and N-tosylhydrazones was reported to construct 2-(1-phenylvinyl)-indoles efficiently. The indole bearing 1, 1-disubstituted alkenes were obtained in one step with short reaction time, in high yields and broad substrate scope. The formed indole derivates could be easily transformed into much more valuable molecules.

3,6-Di(pyridin-2-yl)-1,2,4,5-s-tetrazine capped-silver nanoparticles (TzAgNPs) exhibit an excellent catalytic activity and chemoselectivity for the reduction of various substituted nitroarenes to the corresponding aromatic amines in aqueous medium with sodium borohydride and hydrazine hydrate as a hydrogen donor at room temperature. The reaction kinetics of the reduction of 4-nitrophenol to 4-aminophenol has also been studied to determine the apparent rate constant. The catalyst TzAgNPs efficiently reduces the nitro group under very mild conditions, thus affording excellent yields within very short reaction time (<20 min), and shows high selectivity even in the presence of other sensitive functional groups.

Protection techniques of functional groups within the structure of organic compounds are important synthetic methods against unwanted attacks from various reagents during synthetic sequences. Acetal and thioacetal groups are well known as protective functional groups in organic reactions. In this study, acetalization of carbonyl compounds with diols and dithiols and methoxymethylation of alcohols with formaldehyde dimethyl acetal (FDMA) have been carried out using sulfamic acid-functionalized magnetic Fe3O4 nanoparticles (SA-MNPs) as a heterogeneous solid acid catalyst. Products were characterized by FT-IR and NMR spectroscopies. The structural and electronic properties of some products were computed by quantum mechanical (QM) methods. Depending on the stereochemistry and electronic properties that were obtained by computational results, we have suggested that hyperconjugation plays a key role in the structural properties of 2-phenyl-1,3-dioxolane derivatives, and also the electron transfer between pi-electrons of the aromatic ring with the 3d orbital of S-atoms influences the 2-phenyl-1,3-dithiane derivatives’ structure.

Hydroboration of carbonyl compounds is an important transformation in organic chemistry, and a growing interest in catalysis has focused on abundant and nontoxic base metals. Herein we describe an efficient salen manganese catalyst for the hydroboration of a broad range of carbonyl compounds with pinacolborane. The catalytic reactions proceeded rapidly (>99% conversion in <5 min) at room temperature with very low catalyst loadings. High turnover frequency (up to 5700 h(-1)) was observed under these conditions. Several synthetically important functional groups were tolerated, and chemoselective hydroboration of aldehydes over ketones was achieved. The H/D kinetic isotopic effect of borane was determined to be 2.3. The Hammett correlation plot of a series of para-substituted acetophenone substrates, p-X-C6H6COCH3 (X = H, Me, OMe, NO2, Cl, Br, and CF3) yielded a positive slope of rho = +0.99. The crossover products were detected in the competition reaction of catecholborane and deuterated pinacolborane with acetophenone. The findings indicated a potential borane-mediated pathway that could account for the observation of the crossover products. Formula: C8H7NO3.

A family of ferrocene-based chiral PNP ligands is reported. These tridentate ligands were successfully applied in Mn- catalyzed asymmetric hydrogenation of ketones, giving high enantioselectivities (92%similar to 99% ee for aryl alkyl ketones) as well as high efficiencies (TON up to 2000). In additiondialkyl ketones could also be hydrogenated smoothly. Manganese intermediates that might be involved in the catalytic cycle were analyzed. DFT calculation was carried out to help understand the chiral induction model. The Mn/PNP catalyst could discriminate two groups with different steric properties by deformation of the phosphine moiety in the flexible 5-membered ring.

We report an efficient HCl center dot DMPU assisted one-pot conversion of aldehydes into nitriles. The use of HCl center dot DMPU as both an acidic source as well as a non-nucleophilic base constitutes an environmentally mild alternative for the preparation of nitriles. Our protocol proceeds smoothly without the use of toxic reagents and metal catalysts. Diverse functionalized aromatic, aliphatic and allylic aldehydes incorporating various functional groups were successfully converted to nitriles in excellent to quantitative yields. This protocol is characterized by a broad substrate scope, mild reaction conditions, and high scalability.

Irradiated by visible light, the recyclable (PhTe)(2)-catalyzed oxidative deoximation reaction could occur under mild conditions. In comparison with the thermo reaction, the method employed reduced catalyst loading (1 mol% vs. 2.5 mol%), but afforded elevated product yields with expanded substrate scope. This work demonstrated that for the organotellurium-catalyzed reactions, visible light might be an even more precise driving energy than heating because it could break the Te-Te bond accurately to generate the active free radical catalytic intermediates without damaging the fragile substituents (e.g., heterocycles) of substrates. The use of O-2 instead of explosive H2O2 as oxidant affords safer reaction conditions from the large-scale application viewpoint.

The transformation of alkyl nitriles to symmetrical and asymmetrical secondary aliphatic amines promoted by the hexahydride complex OsH6 ((PPr3)-Pr-i)(2) (1) is described, and the mechanisms of the reactions involved are established. Complex 1 catalyzes the aforementioned transformations of aryl-, pyridyl-, and alkoxy-functionalized alkyl nitriles with linear or branched chains. The formation of the secondary amines involves primary imines, primary amines, and secondary imines as organic intermediates. The reactions take place under mild conditions (toluene, 100 degrees C, and 4 bar of H-2). Stoichiometric reactions of 1 with pivalonitrile and 2-methoxyacetonitrile have allowed us to isolate the trihydride azavinylidene derivatives OsH3{=N=CHR}((PPr3)-Pr-i)(2) (R = Bu-t (3), CH2OMe (4)). Their formation involves the insertion of the N-C triple bond of the substrates into an Os-H bond of the unsaturated tetrahydride OsH4 ((PPr3)-Pr-i)(2) (A), which is generated by reductive elimination of H-2 from the hexahydride precursor. The reaction of these trihydride azavinylidene species with H-2 is the key step for the reduction of the N-C triple bond of the nitriles. In the absence of H-2, the attack of A to the azavinylidene ligand produces the rupture of its C(sp(2))-C(sp(3)) bond. As a consequence of this attack and the presence of primary imines and amines in the reaction media, the binuclear complexes ((PPr3)-Pr-i)(2) H4Os(mu-CN)OsH3{kappa(1)-N-(NH= CHCH2OMe)}((PPr3)-Pr-i)(2) (5) and ((PPr3)-Pr-i)(2)H4Os(mu-CN)OsH3{kappa(1)-N-(NH2CH2CH2OMe)}((PPr3)-Pr-i)(2) (6) have been isolated and characterized by X-ray diffraction analysis, for 2-methoxyacetonitrile. DFT calculations reveal noticeable similarities between the hydrogenations of nitriles to primary imines and those of primary imines to primary amines.

Crystals of (2E)-1-(4-nitrophenyl)-3-(2,3,4-trimethoxyphenyl)prop-2-en-1-one (NPTMP) are grown by slow solvent evaporation technique. The compound purity and presence of functional group elements in the material were identified from the spectroscopic techniques (FT-IR and ?H-NMR). The single-phase formation in the bulk powder crystalline sample has been confirmed from powder XRD analysis. The intermolecular interaction and structure-related parameters were obtained and analyzed by utilizing single-crystal XRD data. Using single-crystal XRD data (CIF file), display of the intermolecular interactions and contribution of H center dot center dot center dot H and H center dot center dot center dot O/O center dot center dot center dot H interaction have been obtained. The molecule is mapped over dnorm, de, di, curvedness, shape index, and electrostatic potential by generating the Hirshfeld’s surface of NPTMP molecule. The linear optical absorbance and optical bandgap of the material have been confirmed by UV-VIS-NIR spectroscopic technique. The thermal stability of the crystal NPTMP is obtained from TGA/DTA/DSC techniques. The surface morphology of the crystal is collected from scanning electron microscopy (SEM) and the electronic contribution of hyperpolarizability parameters is obtained from MOPAC 2016 software. The third-order nonlinear optical properties were studied by the Z-scan technique using CW DPSS laser operating at 532 nm wavelength. The molecule exhibits a comparatively moderate optical limiting response due to reverse saturable absorption (RSA).
