PREPARATION OF COMPOUNDS WITH A PERFLUOROALKYLSULFONYL GROUP

Sulfuryl fluoride is reacted with a perfluoroalkene continuously, for example, under a pressure of up to 2 bars (abs), to form a sulfonyl fluoride or a sulfone. A preferred perfluoroalkene is hexafluoropropene which can be reacted with sulfuryl fluoride to form perfluoroisopropylsulfonyl fluoride.

Carbon-chain isomerization during the electrochemical fluorination in anhydrous hydrogen fluoride - A mechanistic study

The compounds i-C4H9SO2F, i-C3H7SO2F and cyclo-C3 H7C(O)F have been subjected to electrochemical fluorination in anhydrous hydrogen fluoride. The resulting products were fully analyzed by NMR spectroscopy. From the reaction balances, literature data and quantum chemical calculations, a new mechanism for carbon-chain isomerization during the electrochemical fluorination (ECF) is proposed. The key step in the formation of isomeric products is believed to be a ring closure reaction involving carbo-cationic or biradical intermediates.

Process for the synthesis of fluorinated alkyl sulphonyl halides

Preparation of fluorinated alkyl sulphonyl halides having the general formula: STR1 where RIf is fluorinated alkyl group and RIIf is a fluorinated alkyl group or fluorine, X is a halogen atom, and Y is a proton, a halogen atom, or a fluorinated alkyl groups, by reaction of a corresponding fluorinated unsaturated hydrocarbon with sulphuryl halide, wherein the reaction is carried out in the presence of at least catalytic amounts of a fluoride in a solvent comprising compounds having one or more SO and/or SO2 groups incorporated in the compound structure.

Die elektrochemische fluorierung von alkansulfonamiden und alkandisulfonamiden

Alkane sulphonylamides and disulphonylamides are stable in anhydrous (HF)x and undergo quantitative fission of S-N bonds during electrochemical fluorination. Besides NF3, the corresponding perfluoroalkane sulphonyl fluorides and disulphonyl fluorides are formed.
