Abstract

Copper(II)-mediated C–H oxidation reactions have been the focus of extensive attention in recent years. 1,2 Many applications of these reactions are oxidative cyclizations involving heterofunctionalization of arene C–H bonds. 3 Two early examples, reported by the groups of Buchwald 3a and Nagasawa, 3b,c feature copper-catalyzed oxidative cyclization of substituted benzamidines and benzanilides to benzimidazoles (eqn (1)) and benzoxazoles (eqn (2)), respectively. In ...
