The products, plausible intermediates, and their mechanisms of formation in the aprotic diazotization of 2-[(2-acetoxyethyl)-sulfinyl (and sulfonyl)] anilines with isoamyl nitrate have been investigated by experimental and quantum chemical methods. Oxidation of 1, 2, 3- benzthiadiazole with hydrogen peroxide in acetic acid affords 1, 2, 3-benzthiadiazole-1- oxide, 13. The thermal stability of 13 up to 135° C, together with EPR evidence which ...
