Synthesis of 1,1-bis-phosphorus compounds from organoboranes

The facile synthesis of various P-C-P compounds is described, based on the reaction of phosphorus carbenoids with organoboranes, followed by reaction with phosphorus electrophiles. Using this approach, symmetrically and differentially substituted 1,1-bisphosphorus compounds can be obtained in good yields. A number of novel P-C-P motifs are described for the first time.
