Abstract

A previously unknown transformation of aldehydes, ketones, and carboxylic acid derivatives leads to the formation of substituted oxiranes, aziridines, and azirines as shown by DFT and MP2 computations. Formations of 2,2-dimethyloxirane-d₈ from acetone-d₆, phenylazirine-d₂ from benzonitrile and 2- methyl-2-(4-hydroxyphenyl)-oxirane from 4-hydroxyacetophenone were detected experimentally by electrospray ionization mass-spectrometry with a heated desolvating capillary. This reaction is a truly concerted process characterized by high activation barriers (activation enthalpies 320-480 kJmol_-1).
