Abstract

Cobalt(ii) perfluorooctane sulfonate (Co(OPf)₂) acts as a novel homogeneous pre-catalyst for the oxidation of various types of alcohols to carbonyl compounds under atmospheric pressure of molecular oxygen in fluorous biphasic systems. By simple separation of the fluorous phase, which contains only pre-catalyst, the reaction can be repeated several times.
