    摘要： A process for the manufacture of sulphonic acid fluorides of the formula RSO.sub.2 F, wherein R represents a straight-chain or a branched alkyl or cycloalkyl radical is provided. The process is carried out in liquid hydrogen fluoride and comprises reacting thio compounds of the formula R--S--X, wherein R has the indicated meaning and X is hydrogen or --S--R, with nitrogen dioxide and/or dinitrogen tetroxide. The obtained sulfonic acid fluorides are useful intermediates for the manufacture of a great number of other compounds. By means of electrochemical fluorination they can also be converted into the corresponding perfluoroalkylsulphonic acid fluorides, which can be used as a basis for oil and water repellants.

    摘要： .alpha.,.beta.-Unsaturated sulfonic acid salts are prepared by a one step synthesis involving reaction of a di-primary alkyl sulfone, an arylmethyl primary alkyl sulfone, an .alpha.-halo diprimary alkyl sulfone, or an .alpha.-haloarylmethyl primary alkyl sulfone with a carbon tetrahalide and a strong base. The sulfone substrate is reacted with a carbon tetrahalide represented by the formula CBr.sub.m Cl.sub.n F.sub.p where m and n are integers between 0 and 4 inclusive, p is an integer between 0 and 2 inclusive and m+n+p = 4 in the presence of the strong base to form a geminally .alpha.-dihalogenated intermediate and dihalocarbene. The geminally .beta.-dihalogenated intermediate reacts rapidly in situ with the strong base to form an .alpha.,.beta.-unsaturated sulfonic acid salt and a halide salt. The unsaturated sulfonic acid salt may be acidified to form the corresponding acid or reacted with a halogenating agent to form the corresponding acid halide. .alpha.,.beta.-Unsaturated sulfonic acid salts are useful detergents.
