An efficientsynthesis of novel bis[(E)-1-(halomethyl)-2-chlorovinyl] sulfides and selenides via regio- and stereoselective electrophilic addition of SCl2 and SeCl2 to propargyl halides has been developed. The bis(2-chlorovinyl) chalcogenides prepared represent reagents for the synthesis of chalcogen-containing heterocycles and have been used for the synthesis of novel bis(E-chloromethylidene) derivatives
