Hinderedolefins 1–6, by reaction with aminium salts, can afford, in relations to the reaction conditions and the peculiar features of the reagents, different reaction products such as dioxetanes, epoxides, ketones, or homoallylic, allylic and vinylic halogenated derivatives.

The reactions of 4,4-dimethylspiro[adamantane-2,3'-[ 1,2]-diaxetane] (1a) and biadamantylidene-1, 2-dioxetane (2a) in dichloromethane, at different reaction temperatures, with tris(2,4-dibromophenyl) aminium hexachloroantimonate A afford high yields of the rearranged ketones 2-methyladamantyl-methyl ketone (3) and spiro[adamantane-2,4'-homoadamantan-5'-one] (8), respectively. A cation radical monodeoxygenation process is suggested. (C) 1998 Published by Elsevier Science Ltd. All rights reserved.
