Formation of elusive vic-disulfoxides and OS-sulfenyl sulfinates during the m-chloroperoxybenzoic acid (MCPBA) oxidation of alkyl aryl disulfides and their regioisomeric sulfinothioic acid S-esters
Chemical ionization and electron impact mass spectra of thiosulfinates, thiosulfonates and sulfinyl sulfones
摘要:
AbstractThe chemical ionization and electron impact mass spectra of some thiosulfinates, thiosulfonates and sulfinyl sulfones have been studied. The electron impact mass spectra of four of the six thiosulfonates show molecular ions of less than 1%. Inconclusive evidence was obtained for sulfenyl sulfinate type intermediates in the electron impact spectra of thiosulfonates. The electron impact spectra of thiosulfonates were similar to those of thiosulfonates. The chemical ionization (isobutane) mass spectra of thiosulfinates and thiosulfonates generally show protonated molecular ions [MH]+as base peaks and [MH+1]+and [MH+2]+peaks.
