arylation and alkenylation of the alpha-bromoalkenyl phosphonates were investigated with organoboranes and -borates. Arylation was successful with the aryl boronicacids and a palladium catalyst, while alkenylation was found to proceed with alkenyl borates and a nickel catalyst. In addition, an intramolecular Diels-Alder reaction of the diene prepared by the alkenylation afforded the corresponding adduct

coupling reaction of the α-bromoalkenylphosphonates with organoboranes was investigated. The palladium-catalyzed arylation took place successfully with arylboronic acids, while alkenylation proceeded with lithium alkenylborates and a nickel catalyst.
