Abstract :
Organyl thiolate, selenolate or tellurolate anions reacted with alkynylphosphonates 1 to give diethyl 2-(organyl)-2-(organochalcogenyl)vinylphosphonates [β-organochalcogenyl vinylphosphonates] 2 in satisfactory yields. The reaction was stereoselective, giving predominantly or exclusively the (Z)-stereoisomer.
