Rh(III)-catalyzed oxidative synthesis of pyrazoles from azomethines and acrylamides

Abstract

Abstract:

A cationic Rh(III) complex has been developed to catalyze the oxidative coupling of azomethine imines to acrylamides, to give trisubstituted pyrazoles in moderate yield. In this process, the olefinic C-H bond of the acrylamide undergoes C-H activation, and the reaction subsequently proceeds via a different selectivity to that reported for the coupling of acrylate esters.

Key words: Rhodium(III), C-H bond activation, Acrylamide, Azomethine, C-N coupling, Pyrazole
