Spin-trapping e.s.r. experiments employing both MeNO2 (in conjunction with generation of .OH from the TiIII-H2O2 couple in a flow system) and ButNO ( in conjunction with the photolytic decomposition of H2O2) confirm that the reaction of .OH with methionine, S-methylcysteine, and some related compounds effects oxidative decarboxylation.It is proposed that the reaction proceeds via the sequential formation of an hydroxyl adduct at sulphur, a sulphur-centred radical-cation, and a (cyclic) sulphuranyl radical in which the carboxylate function becomes bonded to sulphur.
