Functionalized alkenyl diamino- and dialkoxyboranes were produced regio- and stereoselectively through addition of heteroatom-centered radicals to the corresponding alkynes. The synthetic utility of these reactions was illustrated by the preparation of stereodefined Z- or E-alkenylboronic esters via palladium-catalyzed cross-coupling of the stannylated derivatives.
