Vinylic chalcogenides were synthesized stereospecifically by hydrochalcogenation of propargylic amines or alcohols mediated by cerium(III) chloride. The products were obtained in good yields and with high regio- and stereoselectivities. cerium chloride - vinylic chalcogenides - hydrochalcogenation - selenium - tellurium
