Palladium-Catalyzed Vinylation of Acetylenic Iodides under Solid-Liquid Please-Transfer Conditions

Abstract

Methyl (E)-enynoates and (E)-enyones can be obtained in fair yields by Pd-catalyzed vinylation of 1-iodo-1-alkynes under solid-liquid phase-transfer conditions (potassium carbonate or sodium carbonate/ tetrabutylammonium chloride).
