In situ formation of alkenyl- and alkynylboranes for Diels—Alder reactions by boron—silicon exchange with alkenyl- and alkynylsilanes Academic Article uri icon


  • A variety of alkenylsilanes underwent transmetallation with BBr3 to afford the corresponding alkenyldibromoboranes in solution. Similarly, the transmetallation of alkynylsilanes with BCl3 afforded alkynyldichloroboranes, A number of the alkenyl- and alkynylboranes are novel and useful Diels-Alder dienophiles. An ionic mechanism for the transmetallation is proposed. © 1997 Elsevier Science S.A.
