1,1-Carboboration of 1-Alkynes: A Conceptual Alternative to the Hydroboration Reaction

Abstract

Strongly electrophilic boranes R-B(C(6)F(5))(2) react readily with a variety of 1-alkynes by means of a 1,1-carboboration reaction to yield alkenylborane products, which can subsequently be used as reagents in metal catalyzed cross-coupling reactions.
