Synthesis and reactions of B-vinylcarboranes

Abstract B-Vinylcarboranes were prepared via the palladium-catalyzed cross-coupling of iodocarboranes with vinylmagnesium bromide. Further transformations of the 9-vinyl-1,2-dicarba- closo -dodecaborane side chain yielded bromination, epoxidation, dihydroxylation, oxidative cleavage, radical sulfur addition, and hydroboration/oxidation products.
