The reductive cyclization of α-chloro, bromo- and sulfonyloxycarbonitriles are described. α-Chlorocarbonitriles were reduced by lithium aluminum hydride to afford aziridines in sufficient yields. The Walden inversion was found to take place in the cource of the reductive cyclization of S-α-chloroisocapronitrile. We have found the two-step conversion of aldehydes to 2-mono-substituted aziridines which
Organozinc compounds derived from α-bromonitriles are readily prepared in solution in tetrahydrofuran (THF) and exist in the C metallated form. They condense normally with aldehydes and saturated ketones. A number of new β-hydroxy-nitriles are described. The addition of conjugated unsaturated ketones results in the formation of β-hydroxynitriles or ketonitriles, depending on the nature of the initial

A convenient method for the synthesis of alpha-bromonitriles from aliphatic cyanohydrins using the 2,4,4,6-tetrabromocyclohexa-2,5-dienone complex with triphenylphosphine was developed.
