✦ Synopsis

The cross-coupling reaction of orqanozinc chlorides with (Z)-2bromo-1-alkenylboranes prepared by the bromoboration reaction of 1-alkynes with tribromoborane, proceeds in the presence of a palladium catalyst to give 2,2_disubstituted alkenylboranes, which can be used for the di-or trisubstituted alkene synthesis directly.

Carbometallation

of 1-alkynes' has been regarded as the most reliable
