cross couplingreaction of diethoxyphosphinyldifluoromethylcadmium reagent with aryl iodides was promoted by CuCl under mild conditions to give α,α-difluorobenzylicphosphonates in good yields. A variety of functional groups, including halides, phosphonate, nitro, ketone, carboxylic acid and ester in aryl iodides, could be tolerated. This methodology has been successfully applied to prepare α,α-difluoro
