Copper (I) chloride dissolved in DMSO is effective for Wurtz-type condensation of benzal bromide or dichlorodiphenylmethane affording trans-stilbene and tetraphenylethylene in preparative yields. The reaction of cinnamylidene chloride gives p-terphenyl in addition to all trans-1,6-diphenyl-1,3,5-hexatriene. Olefin-dihalocarbene adducts are also sensitive to this reagent and produce allenes and coupling
溶于DMSO的氯化铜(I)对苯扎溴化物或二氯二苯甲烷的Wurtz型缩合反应有效,可提供反式二苯乙烯和四苯乙烯的制备收率。除所有反式-1,6-二苯基-1,3,5-己三烯外,肉桂酰氯的反应还生成了对-叔苯基。烯烃-二卤卡宾加合物也对该试剂敏感,并会产生丙二烯和偶联产物。的脱卤VIC -dihalides以及关于烯属碳的卤素交换进行说明。
