The present invention relates to a method for preparing α-hydroxy, α-substituted methylenebisphosphonates and phosphonoacetates via addition of Grignard or organoindium reagents to tetraalkyl carbonylbisphosphonates and trialkyl carbonylphosphonoacetates. Also disclosed are compounds so synthesized.
