An efficient Ir-catalyzed cage boron alkenylation of 1-(2'-picolyl)--carboranes with diarylacetylenes has been developed, leading to a wide variety of B-H geminal addition products 1,2-carbon migration of alkynes. The steric effect of cage carbon substituents has a great impact on the regioselectivity of such alkenylation reactions.
