Claim:
A compound of the formula M n+ [OSO 2 CF 3 ] n − , in which M n+ (n=1 or 2) is a ring of the formula X is P or N, and R 1 is hydrogen, or an alkyl group having from 1 to 16 carbon atoms, where the ring is optionally partially subtituted by F, Cl, N(C n F (2n+1−x) H x ) 2 , O(C n F (2n+1−x) H x ), SO 2 (C n F (2n+1−x) H x ), C n F (2n+1−x) H x , where 1≦n≦6 and 0≦x≦2n+1, alkylaryl, aryl and/or a heterocyclic group, and where the alkyl group is optionally partially substituted by F, Cl, N(C n F (2n+1−x) H x ) 2 , O(C n F (2n+1−x) H x ), SO 2 (C n F (2n+1−x) H x ), C n F (2n+1−x) H x , where 1≦n≦6 and 0≦x≦2n+1.
