Abstract

Abstract This work reports the catalytic activity of a large variety of oxo-rhenium (V) complexes (1 mol-%) containing the ligands 2-(2-hydroxy-5-methylphenyl) benzotriazole (Hhmpbta), 2-(2-hydroxyphenyl) benzothiazole (Hhpbt), 2-(2-hydroxyphenyl) benzoxazole (Hhpbo), and 2-(2-hydroxyphenyl)-1H-benzimidazole (Hhpbi) in the deoxygenation of sulfoxides with silanes or boranes as the reducing agents. In general, all of the complexes ...
