Oxidative amidation is a valuable process for the transformation of oxygenated organic compounds to valuable amides. However, the reaction is severely limited using an expensive catalyst and limited substrate scope. To circumvent these limitations, designing a transition-metal-based nanocatalyst via more straightforward and economical methodol. with superior catalytic performances with broad substrate scope is desirable. To resolve the aforementioned issues, the authors report a facile method for the synthesis of nanocatalysts NiO and CuO by the sol-gel-assisted thermal decomposition of [Ni(hep-H)(H2O)4]SO4 (SSMP-1) and [Cu(μ-hep)(BA)]2 (SSMP-2) [hep-H = 2-(2-hydroxylethyl)pyridine; BA = HOBz] as single-source mol. precursors (SSMPs) for the oxidative amidation of benzyl alc., benzaldehyde, and BA by using DMF as the solvent and as an amine source, in the presence of tert-butylhydroperoxide (TBHP) as the oxidant, at T = 80°. In addition to nanocatalysts NiO and CuO, the authors’ previously reported Co/CoO nanocatalyst (CoNC), derived from [CoII(hep-H)(H2O)4]SO4 (A) as an SSMP, was also explored for the aforementioned reaction. Also, the authors have carefully studied the difference in the catalytic performance of Co-, Ni-, and Cu-based nanoparticles synthesized from the SSMP for the conversion of various oxygenated and unsaturated organic compounds to their resp. amides. CuO showed an optimum catalytic performance for the oxidative amidation of various oxygenated and unsaturated organic compounds with a broad reaction scope. Finally, CuO can be recovered unaltered and reused for several (six times) recycles without any loss in catalytic activity. In the experimental materials used by the author, we found 2-(2-Hydroxyethyl)pyridine(cas: 103-74-2SDS of cas: 103-74-2)
2-(2-Hydroxyethyl)pyridine(cas: 103-74-2) belongs to pyridine. When pyridine is adsorbed on oxide surfaces or in porous materials, the following species are commonly observed: (i) pyridine coordinated to Lewis acid sites, (ii) pyridine H-bonded to weakly acidic hydroxyls, and (iii) protonated pyridine. At high coverage, physisorbed pyridine and protonated dimers can also be observed.SDS of cas: 103-74-2
