摘要
Prepn. of cpds. contg. a perfluoroalkyl or perfluoroalkenyl gp., esp. derivs. of acids of formula: RFCOOH and RFSO2H, comprises reacting a perfluoro cpd. of formula: RFX (where RF is a 2-12C perfluoroalkyl or perfluoroalkenyl radical and X is Cl, Br or I), with an appropriate reactant, esp. CO2 and SO2, in the presence of a dispersion in a sulphoxide solvent of a metallic couple cpd. of a metal M, selected from Group 1b,2a,2b or 3a metals and a metal M2 having a lower electrochemical potential than (and which deposits on) metal M. Acids RF COOH and RFSO3H (prepd. from RFSO2H) are surfactants and also intermediates to textile, paper and leather treating agents and other surfactants.
