Copper-catalyzed cross-coupling of bromozinc-difluoromethylphosphonate with iodo/bromo-aryl triazenes†
Abstract
A versatile method for the preparation of aryldifluoromethylphosphonates has been developed. This represents the first example of copper-catalyzed difluoroalkylation of ArBr and provides a useful and facile access to diverse aryldifluoromethylphosphonates that are difficult to prepare otherwise.
