Thermolysis of arenesulphohydroxamic acid (Ar=Ph or p-tolyl) by heating at its melting point in air for 10 min gave nitric oxide, sulphurdioxide, and ammonia together with the corresponding arene, biaryl, diaryl sulphide, diaryl disulphide, diaryl sulphone, diaryl disulphone, thiophenol, aryl ammonium sulphonate, arene sulphonic acid and ammonium sulphite.Similar results were obtained on photolysis in acetone solution for 20 h at room temperature.The photolysis was found to be an intramolecular process as shown by cross-over experiment.A free-radical mechanism starting by homolysis of the S-N bond was suggested to account for the observed results.
