Direct oxidation of alcohols catalysed by heterometallic complex [CuNi(bz)3(bpy)2]ClO4 to aldehydes and ketones mediated by hydrogen peroxide as a terminal oxidant

We report herein a ligand and additive- free [CuNi(bz)3(bpy)2]ClO4 catalyst system that efficiently and selectively catalyses the oxidation of a range of primary and secondary benzylic alcohols, 1 – heteroaryl alcohols, cinnamyl alcohol, and aliphatic alcohols mediated by hydrogen peroxide to the corresponding aldehydes and ketones, respectively.Graphical abstractHeterobimetallic copper-zinc coordination complex as an efficient catalyst for the oxidation of alcohols to aldehydes under mild condition in water in 30 % aqueous H2O2.
