A highly efficient and stereoselective method for the synthesis of (1Z)-1,2-dihalo-3-vinyl-1,3-dienes featuring palladium-catalyzed coupling of haloalkynes and 2,3-butadienyl acetates was developed. The resulting products were smoothly converted into cis-1,2-dihalostyrene derivatives using the Diels-Alder/aromatization sequence.
