Abstract

Cpds. of formula (I) : RfSO2H (where Rf is an aliphatic or cycloaliphatic perfluorinated 1-12C residue) are prepd. by reacting RfSO2F with hydrazine (anhydrous, hydrate or aq. soln., pref. in a 2- or 3-fold molar excess) at >30 degrees C in the presence of a solvent to give a hydrazonium salt, and adding an acid, pref. HCl gas, HCl soln., H3PO4 or H2SO4, to isolate (I), which is pref. purified by vacuum distillation or crystn. (I) are new (except CF3SO2H2), highly reactive cpds. useful as inters.
