Copper-catalyzed direct selenation of substituted 2-bromo-N-phenylbenzamide substrates with elemental selenium powder provided a series methoxy-substituted isoselenazolones via the C-Se and Se-N bond formations. Phenolic have been obtained by O-demethylation corresponding analogues using boron tribromide. Some structurally characterized X-ray single-crystal analysis. The glutathione peroxidase (GPx)-like antioxidant activity has evaluated both in thiophenol coupled-reductase assays. All showed good GPx-like activities assay. ferric-reducing power phenolic antioxidants also evaluated. best were found to be agents. single electron transfer, hydrogen atom proton-coupled transfer mechanisms for properties all catalysts supported density functional theory calculations. catalytic cycle was proposed one involving diselenide, selenenyl sulfide, selenol, selenenic acid as intermediates 77Se{1H} NMR spectroscopy.
