Abstract 1,1‐Bis(4‐alkylthiophenyl)‐1‐alkenes were conveniently and efficiently prepared from alkyl phenyl sulfides and acyl chloridesvia a tandem Friedel–Craftsacylation and alkylation in the presence of anhydrous aluminum chloride. The scope, limitation, and mechanism of the tandem reaction were also discussed.

AbstractA novel route to 2,2‐diarylvinyl phenyl selenides is reported by dehydration of the corresponding 2,2‐diaryl‐2‐hydroxyethyl phenyl selenides, prepared by oxyphenylselenenylations of the corresponding 1,1‐diarylethylenes, upon treatment with p‐toluenesulfonic acid.
