Tris(methylseleno)- and tris(phenylseleno)boranes added to acetylenes to afford methylseleno- and phenylseleno-substituted Z-vinylselenides in high yields.The addition reactions proceeded by way of free radicals and were applied to cyclization reactions o

Tris(phenylseleno)borane and tris(methylseleno)borane reacted with terminal acetylenes to afford (Z)-vinyl selenides.This reaction was initiated by oxygen and the intermediates were vinyl radicals.This radical reaction could be applied to the intramolecular free radical cyclisation of enynes and some heterocycles and carbocycles were synthesised.This novel method could be also employed in the synthesis of α-kainoid derivatives.
