Abstract
The treatment of 1-phenylthioacetylenes with phenylselenolate and butyl orphenyltellurolate anions generated by the reaction of the corresponding dichalcogenide with NaBH4 in aqueous ethanol results in the formation of mixed 1,2-bis(organylchalcogeno)-1-alkenes of Z configuration. The phenylthio group acts as a directing and activating group for the nucleophilic additionof the chalcogenate anions (C) 2001 Elsevier Science Ltd. All rights reserved.
