Tris(methylseleno)- and tris(phenylseleno)boranes added to acetylenes to afford methylseleno- and phenylseleno-substituted -vinylselenides in high yields. The addition reactions proceeded by way of free radicals and were applied to cyclization reactions of enyne compounds. The radical cyclization provided pyrrolidine derivatives diastereoselectively.
