The α-elimination of hydrogen chloride from 1-chloroalkanes, and the α-elimination of iodine from 1,1-diiodoalkanes have been studied with particular emphasis on the formation of isomeric cyclopropanes. The product ratios are compared to those obtained by the pyrolysis of diazoalkanes. The intermediates produced by the α-eliminations are found to insert more selectively into secondary and tertiary
已经研究了从1-氯代烷烃中的氯化氢的α-消除和从1,1-二碘代烷烃中的碘的α-消除,特别着重于异构化环丙烷的形成。将产物比率与通过重氮链烷烃热解获得的比率进行比较。发现由α-消除产生的中间体更选择性地插入到仲和叔碳氢键中。用Na,Li和Mg处理1,1-二碘链烷烃主要产生环丙烷,而Zn和Cu通过Wagner-Meerwein型重排产生烯烃。
