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[Rf.sup.1 OSO.sub.2 NSO.sub.2 ORf.sup.2 ].sub.n wherein Rf.sup.1 and Rf.sup.2 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 Rf.sup.3 OH wherein Rf.sup.3 represents the same of different groups which are identical with Rf.sup.1 and Rf.sup.2. The second compound has a fluorocarbon sulfonic acid ester group and is represented by a general formula of --[M[N--SO.sub.2 ORf.sup.4 OSO.sub.2 ].sub.n ].sub.m -- wherein Rf.sup.4 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 HORf.sup.5 OH wherein Rf.sup.5 represents a bivalent organic group which is identical with Rf.sup.4. 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.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
