Abstract: NEW STABLE SULFONAMIDES CONTAINING A CF2 GROUP ADJACENT TO NITROGEN ARE OBTAINED BY REACTING N-MONO-SUBSTITUTED SULFONAMIDES WITH FLUORO-OLEFINS OR THE ALKALI METAL SALTS OF SAID SULFONAMIDES WITH FLUORO-HALOALKANES. THE PRODUCTS ARE USEFUL AS REACTIVE INTERMEDIATES FOR A VARITETY ORGANIC SYNTHESES AND-OWING TO THEIR POLARITY AND HIGH BOILING POINTS-AS VALUABLE SOLVENTS FOR SPARINGLY SOLUBLE ORGANIC OR INORGANIC COMPOUNDS.
