Using a prevalent palladium catalyst, Pd(PPh3)4, a quantitative cross-coupling of various H-phosphonate diesters with aryl and vinyl halides was achieved in less than 10 min under microwave irradiation. The reactions occurred with retention of configuration at the phosphorus center and in the vinyl moiety.
