Abstract
(E)-α-Selenenylvinylsilanes have been synthesized stereoselectively via the hydromagnesiation of alkynylsilanes, followed by the reaction with arylselenenyl bromides. (E)-α-Selenenylvinylsilanes can undergo the desilylation reaction in the presence of a catalytic amount of hydriodic acid to give (E)-vinyl selenides in high yields.
Key words
hydromagnesiation - (E)-α-selenenylvinylsilane - alkynylsilane - stereoselectivity - (E)-vinyl selenide
