An unprecedented copper-mediated oxidative difluoromethylenation of aryl boronic acids with α-silyldifluoromethylphosphonates has been developed, allowing rapid access to a wide range of aryldifluorophosphonates containing various functional groups. This method provides a complementary and alternative method to Cu-mediated cross-couplings of aryl iodides with metalated difluoromethylphosphonates.
