摘要
Summary of main observation and conclusion Outstanding accomplishments have been achieved in the chemistry of difluorocarbene,but transitionmetal-catalyzed transfer of difluorocarbene for coupling remains a challenging task.Herein,we describe a Pd-catalyzed coupling of difluorocarbene with two aryl carbon centers to give difluoromethylenation products,which cannot be obtained by any previous difluorocarbene-transformation method.
