Coumarin-surfactant modified polyoxometalate catalyzed cross dehydrogenative coupling of benzyl alcohol with the para-C–H of unprotected aniline

Abstract

This paper presents a novel method for synthesizing para-aminobenzophenone and its derivatives (p-ABPs) using a coumarin-surfactant modified polyoxometalate as the catalyst. Preliminary mechanistic studies indicate that the reaction has undergone an oxidative cross dehydrogenative coupling process. This method has the advantages of an easy process, a convenient raw material source, safe and green oxidants, and tolerances of several functional groups.
