In the reaction of CH3SO2F with hydroxylamine the products CH3SO2N(H)OH, H3NOH(+)CH3SO3(-), and H5N2(+)CH3SO3(-) are formed.H2NO-Si(CH3)3 reacts with CH3SO2F to yield mainly H5N2(+)CH3SO3(-).These results are explained by consecutive reactions of the intermediate CH3SO2NH2. - Key words: Sulfonic Acid Fluorides, Hydroxylamines
