In the presence of catalytic amount of bismuth(III) chloride, the reactions of acyl chlorides or vinyl chlorides with arenes afforded 1,1-diarylalkenes 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
在催化量的氯化铋(III)的存在下,酰氯或氯乙烯与芳烃的反应可提供1,1-二芳基烯烃,分离产率为25-82%。在酰氯与芳烃反应的情况下,该程序包括最初的Friedel-Crafts酰化反应,随后形成的氯乙烯和最终的另一个芳烃分子与氯乙烯的Friedel-Crafts型乙烯基化反应。本文报道了路易斯酸催化的氯乙烯CCl键的首次裂解及其在多取代烯烃合成中的应用。
