Detection of aromatic sulphinyl (ArSO·) radicals during the photolysis and thermolysis of S-aryl arenethiosulphonates and diaryl sulphoxides
Abstract
Evidence has been obtained using e.s.r. spectroscopy that arenesulphinyl radicals (ArSO·) are produced during the thermal and photolytic homolysis of both diaryl sulphoxides and S-aryl arenethiosulphonates, in the latter case via the initial production of the corresponding sulphonyl and thiyl radicals, ArSO2· and ArS·, respectively.
