Abstract 1,1‐Bis(4‐alkylthiophenyl)‐1‐alkenes were conveniently and efficiently prepared from alkyl phenyl sulfides and acyl chlorides via a tandem Friedel–Crafts acylation and alkylation in the presence of anhydrous aluminum chloride. The scope, limitation, and mechanism of the tandem reaction were also discussed.
摘要 以烷基苯基硫化物和酰氯为原料,在无水氯化铝存在下,通过串联 Friedel-Crafts 酰化和烷基化反应,可以方便有效地制备 1,1-双(4-烷基硫代苯基)-1-烯烃。还讨论了串联反应的范围、局限性和机理。
