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
