Supported ruthenium catalyst for the heterogeneous oxidation of alcohols with molecular oxygen

Abstract

Round and round it goes! A supported ruthenium catalyst, easily prepared by treatment of RuCl3 with γ-Al2O3, is an efficient heterogeneous catalyst for the oxidations of alcohols with 1 atm of molecular oxygen or air without any additives (see scheme). The spent catalyst was recyclable without an appreciable loss of the catalytic activity and selectivity for the oxidation.
