Freshly prepared nano NiO, NiO supported HAP, TiO2, ZrO2 and γ-Al2O3 and metal ion substituted nickel oxide (Ni1−xMxO, M&nbsp;=&nbsp;Co, Cu and Mn) have been tested for hydration of aromatic nitriles. Mn substituted compound of nominal composition, Ni0.7Mn0.3O was found to be the highly active catalyst. The reaction was carried out in autoclave using water as a solvent and the reaction time varied between 2 and 24&nbsp;h for heterocyclic cyano nitriles to methyl benzonitriles.

Investigation of nano NiO, supported and metal ion substituted NiO for selective hydration of aromatic nitriles to amides

The synthetic chemists always look for developing new catalysts, sustainable catalysis, and their applications in various organic transformations. Herein, we report a new class of water-soluble complexes, (Ar-tpy)RuII(ACN)3, utilizing designed terpyridines possessing electron-donating and -withdrawing aromatic residues for tuning the catalytic activity of the Ru(II) complex. These complexes displayed excellent catalytic activity for several oxidative organic transformations including late-stage C-H functionalization of aldehydes with NH2OR to valuable primary amides in nonconventional aqueous media with excellent yield. Its diverse catalytic power was established for direct oxo-scissoring of a wide range of alkenes to furnish aldehydes and/or ketones in high yield using a low catalyst loading in the water. Its smart catalytic activity under mild conditions was validated for dioxygenation of alkynes to highly demanding labile synthons, 1,2-diketones, and/or acids. This general and sustainable catalysis was successfully employed on sugar-based substrates to obtain the chiral amides, aldehydes, and labile 1,2-diketones. The catalyst is recovered and reused with a moderate turnover. The proposed mechanistic pathway is supported by isolation of the intermediates and their characterization. This multifaceted sustainable catalysis is a unique tool, especially for late-stage functionalization, to furnish the targeted compounds through frequently used amidation and oxygenation processes in the academia and industry. © 2019 American Chemical Society.
