Abstract

A homogeneous visible light photoredox TEMPO-mediated selective oxidation of primary alcohols to the corresponding carbonyl compounds was developed using molecular oxygen from air as the terminal oxidant. Ru(bpy)3(PF6)2 (bpy: bipyridyl) and Ir(dtb-bpy)(ppy)2(PF6) (dtb-bpy: 4,4′-di-tert-butyl-2,2′-bipyridyl; ppy: 2-phenylpyridine) were used as the sensitizers.
