Utilization of a Copper on Iron Catalyst for the Synthesis of Biaryl Systems and Benzoxazines via Oxidative Arylation of Anilide Derivatives

Abstract

Heterogeneous copper on iron catalyst serves as an efficient alternative copper source for arylation reactions using hypervalent iodonium salts. The copper(0) catalyst affords meta-arylation of pivalanilides, while 2-ethynylanilides undergo oxidative carbo­arylation–ring closure with diaryliodonium salts.

Key words

biaryls - copper - coupling - heterocycles - iron
