FIVE-MEMBERED ZIRCONACARBOCYCLES IN THE SYNTHESIS OF PHOSPHOLANES AND PHOSPHOLS

The review summarizes and systematizes data on methods for the synthesis of substituted phospholanes and phospholes based on the reaction of five-membered zirconacarbocycles obtained in situ by catalytic cyclometallation of unsaturated compounds (alkenes, alkynes or dienes) into phosphacarbocycles using alkyl (aryl) phosphorus dihalides. The high reactivity of zirconacarbocycles allows one to obtain cyclic organophosphorus compounds (OPCs) under mild conditions, with high yields and in virtually one preparative step, which makes this approach extremely popular.
