Abstract
1. Biological and biomimetic oxidations of thioethers are reviewed.
2. γ-Radiolysis, pulse radiolysis, photochemical, chemical, and electrochemical methods for generating sulphur cation radicals are discussed and exemplified.
3. The major reactions of sulphur cation radicals: nucleophilic attack, electron transfer, decarboxylation, reaction with O2, C-S, C-C, and α-C-M bond cleavages, sulphur abstraction, and rearrangements are presented.
