Uses

Benzynes were generated from o-(trimethylsilyl) phenols using nonafluorobutanesulfonyl fluoride (NfF) by a domino process.Nonafluorobutanesulfonyl fluoride (nonaflyl fluoride, C 4 F 9 SO 2 F, NfF) is the most widely used commercially available reagent for the synthesis of nonaflates.

PARTIELL NICHTFLUORIERTE VERBINDUBGEN BEI DER ELECTROCHEMISCHEN FLUORIRUNG VON SULFOLEN

The sulfonylfluorides C3F7CHFSO2F and C3F7CH2SO2F have been isolated and characterized as byproducts of the electrochemical fluorination of 2,5-dihydrothiophene-1,1-dioxide (sulfolene).A mechanism is given for the formation of these byproducts.

N-oxide of perfluorobutylsulfonyl(3-dimethylaminopropyl)amine as well as preparation method and application thereof

The invention discloses an N-oxide of perfluorobutylsulfonyl(3-dimethylaminopropyl)amine as well as a preparation method and application of the N-oxide, and belongs to the field of fluorine-containingfine chemicals. According to the invention, the perfluorobutylsulfonyl(3-dimethylaminopropyl)amine is produced by a one-pot method and serves as a aqueous film-forming foam extinguishing agent, wherein the product is prepared by reacting perfluorobutyl sulfonyl fluoride, alkyl diamine, a solvent, an acid-binding agent and an oxidant, and filtering the components to remove byproduct hydrochlorideand a distillation solvent, thereby obtaining the product. The method has the advantages of few production steps, shortened reaction time, low cost, reduced three wastes, no pollution, high yield andgood quality.

METHOD FOR RECOVERING SULFONIC ESTERS OR SULFONYL HALIDES FROM SALTS OF SULFONIC ACIDS

A method for the obtainment of an ester or a halide of a fluorinated sulfonic acid from an salt of a sulfonic acid is herein disclosed. The method is particularly useful for recovering waste sulfonate salts from reaction mixtures obtained by reaction of sulfonic esters of alcohols having a pKa lower than 15 with nucleophile compounds.
