presence of phenylallylamine produces a rearranged product in poor yield (11–15%) whereas the reaction of allyl alcohol with arylchlorocarbene gives exclusively diallyl acetals in high yield (70%). The rate constants for these reactions were obtained by laser flash photolysis. Allyl phenyl ether forms a cyclopropanated product when treated with arylchlorocarbene. The different behaviour of these compounds
当在烷基或烯丙基取代的胺存在下进行芳基
氯二
氮丙啶的光解时,N-烷基或 N-烯丙基取代的胺作为唯一的高产率 (64-93%) 产物产生。在苯
烯丙胺存在下光解产生重排产物,产率低(11-15%),而
烯丙醇与芳基
氯卡宾反应仅以高产率(70%)得到二烯丙
缩醛。这些反应的速率常数是通过激光闪光光解获得的。当用芳基
氯卡宾处理时,
烯丙基苯基醚形成
环丙烷化产物。这些化合物的不同行为可归因于这些化合物在氮和氧中心的亲核性,当后者进行上述取代时。使用
烯丙基苯基醚时
环丙烷化产物的形成不同于文献中报道的双(甲氧基羰基)卡宾与
烯丙基醚的反应。这种
环丙烷的形成...
