Abstract
A process for producing N-fluorosulfonamides by reaction of a sulfonamide with fluorine in a solvent mixture of halogenated hydrocarbon an nitrile is described together with new N-fluorosulfonamides which are produced in accordance with this process.
Claims16
A process for producing N-fluorosulfonamides comprising reacting a sulfonamide corresponding to the Formula (I):
- R.sup.1 --SO.sub.2 --NH--R.sup.2 (I)
- in which
- R.sup.1 represents alkyl with 1 to 10 C-atoms or alkyl with 1 to 10 C-atoms substituted by at least 1 F-atom, or aryl or aryl substituted by 1 to 5 substituents independently selected from the group consisting of F-atoms, CF.sub.3 -groups, and CH.sub.3 - groups, with the proviso that not more than 2 substituents may be CF.sub.3 -groups or CH.sub.3 -groups, and
- R.sup.2 represents alkyl containing 1 to 6 C-atoms,
- with elemental fluorine in a solvent mixture comprising a halogenated hydrocarbon and a nitrile, and recovering the resulting N-fluorosulfonamide from the reaction mixture.
