US 2001/0012903 A1 · Amines or salts thereof and methods of preparing same

Abstract

The invention relates to a first compound which is a first amine or a first salt thereof, and to a second compound which is a second amine or a second salt thereof. The first compound has a fluorocarbon sulfonic acid ester group and is represented by a general formula of M[Rf1OSO2NSO2ORf2]n wherein Rf1 and Rf2 represent the same or different fluorine-containing monovalent organic groups. The first amine is prepared by reacting bis(chlorosulfonyl)amine with a fluoroalcohol represented by a general formula of Rf3OH wherein Rf3 represents the same of different groups which are identical with Rf1 and Rf2. The second compound has a fluorocarbon sulfonic acid ester group and is represented by a general formula of —[M[N—SO2ORf4OSO2]n]m— wherein Rf4 represents a fluorine-containing bivalent organic group. The second amine is prepared by reacting bis(chlorosulfonyl)amine with a fluorodiol represented by a general formula of HORf5OH wherein Rf5 represents a bivalent organic group which is identical with Rf4. The first and second salts are respectively prepared by reacting the first and second amines with a compound selected from ammonia, quaternary ammonium compounds, hydroxides of, oxides of, carbonates of, halides of, fluorides of, chlorides of, bromides of, iodides of, and acetates of particular elements. The first and second compounds are fully expected to be usable as catalyst and the like, in the synthesis of organic compounds.
