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.

Condensation of beta-(2-pyridyl)enamine and alpha,beta-unsaturated ketone in the presence of FeCl3 under air afforded highly substituted pyridines. In this transformation, FeCl3 acted as not only an acid catalyst but also an oxidant for the intermediate dihydropyridine. The substituents could be easily modified by altering the substrates to obtain tri- and tetraarylpyridines including bipyridines and terpyridine. Synthesis of differently substituted pentaarylpyridines was consequently achieved via only three steps from commercially available reagents with simple experimental manipulations.

Deprotonation of the Mn-I NHC-phosphine complex fac-[MnBr(CO)(3)(k(2)P,C-Ph2PCH2NHC)] (2) under a H-2 atmosphere readily gives the hydride fac-[MnH(CO)(3)(k(2)P,C-Ph2PCH2NHC)] (3) via the intermediacy of the highly reactive 18-e NHC-phosphinomethanide complex fac-[Mn-(CO)(3)(k(3)P,C,C-Ph2PCHNHC)] (6a). DFT calculations revealed that the preferred reaction mechanism involves the unsaturated 16-e mangana-substituted phosphonium ylide complex fac-[Mn(CO)(3)(k(2)P,C-Ph2P=CHNHC)] (6b) as key intermediate able to activate H-2 via a non-classical mode of metal-ligand cooperation implying a formal lambda(5)-P-lambda(3)-P phosphorus valence change. Complex 2 is shown to be one of the most efficient pre-catalysts for ketone hydrogenation in the Mn-I series reported to date (TON up to 6200).

The synthesis, electronic structure, and reactivity of a uranium metallacyclopropene were comprehensively studied. Addition of diphenylacetylene (PhC equivalent to CPh) to the uranium phosphinidene metallocene [eta(5)-1,2,4-(Me3C)(3)C5H2](2)U=P-2,4,6-tBu(3)C(6)H(2) (1) yields the stable uranium metallacyclopropene, [eta(5)-1,2,4-(Me3C)(3)C5H2](2)U[eta(2)-C2Ph2] (2). Based on density functional theory (DFT) results the 5f orbital contributions to the bonding within the metallacyclopropene U-(eta(2)-C=C) moiety increases significantly compared to the related Th-IV compound [eta(5)-1,2,4-(Me3C)(3)C5H2](2)Th[eta(2)-C2Ph2], which also results in more covalent bonds between the [eta(5)-1,2,4-(Me3C)(3)C5H2](2)U2+ and [eta(2)-C2Ph2](2-) fragments. Although the thorium and uranium complexes are structurally closely related, different reaction patterns are therefore observed. For example, 2 reacts as a masked synthon for the low-valent uranium(II) metallocene [eta(5)-1,2,4-(Me3C)(3)C5H2](2)U-II when reacted with Ph2E2 (E=S, Se), alkynes and a variety of hetero-unsaturated molecules such as imines, ketazine, bipy, nitriles, organic azides, and azo derivatives. In contrast, five-membered metallaheterocycles are accessible when 2 is treated with isothiocyanate, aldehydes, and ketones.

The mode of asymmetric induction in an enantioselective intramolecular allylic substitution reaction catalyzed by a combination of palladium and a chiral phosphoric acid was investigated by a combined experimental and statistical modeling approach. Experiments to probe nonlinear effects, the reactivity of deuterium-labeled substrates, and control experiments revealed that nucleophilic attack to the pi-allylpalladium intermediate is the enantio-determining step, in which the chiral phosphate anion is involved in stereoinduction. Using multivariable linear regression analysis, we determined that multiple noncovalent interactions with the chiral environment of the phosphate anion are integral to enantiocontrol in the transition state. The synthetic protocol to form chiral pyrrolidines was further applied to the asymmetric construction of C-O bonds at fully substituted carbon centers in the synthesis of chiral 2,2-disubstituted benzomorpholines.

The latter was treated with excess hydrazine hydrate, and the resulting tetrahydrazide was converted to tetrakis1,2,4-triazolyl derivative via cyclization with ethanolic potassium hydroxide, carbon disulfide, and hydrazine hydrate. In the final stage, cyclocondensation with substituted chalcones afforded the target products. The structure of the newly synthesized compounds was confirmed by elemental analyses and FT-IR and NMR spectra, and their antimicrobial activities against some bacterial and fungal strains were estimated by the disc diffusion method.

A general and efficient boronic acid catalyzed Friedel-Crafts alkylation of arenes with benzylic alcohols was previously developed for the construction of unsymmetrical diarylmethane products (X. Mo, J. Yakiwchuk, J. Dansereau, J. A. McCubbin and D. G. Hall, J. Am. Chem. Soc., 2015, 137, 9694). Highly electron-deficient benzylic alcohols, however, were ineffective coupling partners due to the increased difficulty of C-O bond ionization. Herein, we report the use of perfluoropinacol as an effective co-catalyst to improve the reactivity of a boronic acid catalyst in the Friedel-Crafts benzylations of electronically deactivated primary and secondary benzylic alcohols. According to spectroscopic studies, it is believed that perfluoropinacol condenses with the arylboronic acid catalyst to form a highly electrophilic and Lewis acidic boronic ester. This in situ formed species enables a more facile ionization of the benzylic alcohols likely through a mode of activation promoted by a Lewis acid assisted hydronium Bronsted acid generated from the interactions of the transient boronic ester with hexafluoroisopropanol solvent and water.

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.

The appropriate pyridine-2(1H)-thiones were reacted with an equivalent amount of 5-(chloromethyl)-2-hydroxybenzaldehyde in ethanol in the presence of potassium hydroxide to give the corresponding 2-hydroxybenzaldehyde derivatives in excellent yields. The latter derivatives were taken as key synthons for the preparation of the target hybrids. Therefore, 2-hydroxybenzaldehydes were reacted with benzoylglycine in acetic anhydride in the presence of fused sodium acetate at 100 degrees C for 6 hours to afford a new series of nicotinonitrile-coumarin hybrids. The in vitro acetylcholinesterase inhibitory activities were estimated for the new coumarins. The results were expressed as the inhibition percentage of the tested hybrids at concentration of 25 nM, compared to donepezil as a reference (inhibition percentage of 70.5). Coumarin hybrids linked to 6-(4-nitrophenyl) or 6-(4-chlorophenyl)-4-phenylnicotinonitrile exhibited more effective inhibitory activities than donepezil with inhibition percentages of 94.1 and 72.3, respectively. The new coumarins were tested for their free radical-scavenging capabilities against DPPH. Furthermore, some new coumarins were tested for in vitro cytotoxic activity against each MCF-10A, MCF-7, Caco2, and HEPG2. The new hybrids showed cytotoxicity in micromolar range (IC(50)of 3.5-13.9 mu M) against all tested cell lines. These results clearly demonstrated that the hybrids being tested are not cytotoxic at the concentration required to inhibit acetylcholinesterase effectively.
