Treatment of phenylcyclopropane with silver(I) acetate–iodine or thallium(I) acetate–iodine gives, as the major products, 1,3-disubstituted phenylpropanes resulting from cyclopropane ring opening, and in some cases, from solvolysis of intermediate iodo-acetates. Similar products are given with silver(I) trifluoroacetate–iodine but in this case aromatic iodination also occurs. Treatment of norcarane
用乙酸碘化银(I)或乙酸碘化th(I)处理苯基环丙烷,作为主要产物,是由环丙烷开环以及某些情况下由中间碘代乙酸盐的溶剂化产生的1,3-二取代苯基丙烷。三氟乙酸银(I)-碘也可提供类似的产品,但在这种情况下也会发生芳族碘化。用相同的试剂处理正二十烷也会导致开环,但此处的副产物是通过消除和随后添加而产生的。两种底物对烯烃对每种试剂的反应性均不如烯烃。讨论了反应机理。据报道其他涉及亲电碘与苯基环丙烷和正戊烷的试剂系统的作用。
