In the presence of catalytic amount of bismuth(III) chloride, the reactions of acyl chlorides or vinyl chlorides with arenes afforded 1,1-diarylatkenes in 25-82% isolated yield. In the case of the reaction of acyl chlorides with arenes, the procedure includes an initial Friedel-Crafts acylation, subsequent formation of vinyl chlorides and final Friedel-Crafts-type vinylation of another arene molecule with vinyl chloride. This paper reports the first Lewis acid-catalyzed cleavage of the C-Cl bond of vinyl chloride and its application in the synthesis of multiply subtituted alkenes.
