Difluoromethylated arenes are scaffolds of great interest. We report herein a mild and general method for the introduction of the CF2PO(OEt)2 moiety into arenes. The CuCF2PO(OEt)2 species, which is generated in situ from the corresponding silylated derivatives, in combination with aryl diazonium salts furnished the highly valuable aryl difluoromethylphosphonates in moderate to good yields. This represents
