The α-elimination of hydrogenchloridefrom 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
