A Kinetic-Electron Spin Resonance Study of the Self-reactions of Some Aromatic and Aliphatic Sulphonyl Radicals and Aromatic Sulphinyl Radicals

A variety of aromatic and aliphatic sulphonyl radicals (RSO2.) have been found to undergo diffusion-controlled self-reaction in solution (with 2kt typically ca. 109 dm3 mol-1 s-1); reaction proceeds somewhat slower for some sterically hindered arenesulphonyl radicals (ArSO2.) and for some arenesulphinyl analogues (ArSO.).The observation of curved Arrhenius plots for some ArSO2. radicals, as well as the detection of ArSO. from sulphonyl precursors under steady-state conditions, is attributed to the thermal decomposition of an unstable intermediate formed by dimerisation (sulphur-to-oxygen) of ArSO2..A thermodynamic and kinetic analysis is presented.
