Patent ID: 6841304

Claim:
An ionic compound having a cation of the onium type with at least one heteroatom comprising N, O, S or P bearing the positive charge and the anion including, in whole or in part, at least one imide ion at the type (FX 1 O)N−(OX 2 F) wherein X 1 and X 2 are the same or different and comprise SO or PF, wherein the compound comprises at least an anion selected from Cl − ; Br − ; I − ; NO 3 − ; M(R 10 ) 4 − ; A(R 10 ) 6 − ; R 11 YO 2 − ; R 11 YONZ 1− ; R 11 YOCZ 2 Z 3 ; 4,5-dicyano-1,2,3-triazole; 3,5-bis(R F )-1,2,4-triazole; tricyanomethane; pentacyanocyclopentadiene; pentakis(trifluoromethyl)cyclopentadiene; and barbituric acid, and; M is B, Al, Ga or Bi; A is P, As and Sb; R 10 is a halogen; R 11 represents H, F, alkyl, alkenyl, aryl, arylalkyl, alkylaryl, arylalkenyl, alkenylaryl, dialkylamino, alkoxy or thioalkoxy, each having from 1 to 18 carbon atoms and being unsubstituted or substituted with one or more oxa, thia, or aza substituents, and wherein one or more hydrogen atoms are optionally replaced with halogen in a ratio of 0 to 100%, and eventually being part of polymeric chain; Y represents C, SO, S═NCN, S═C(CN) 2 , PR 11 , P(NCN)R 11 , P(C(CN) 2 )R 11 , and when Y is P(NCN)R 11 or P(C(CN) 2 )R 11 , then R 11 YO 2 , R 11 YONZ 1 , and R 11 YOCZ 2 Z 3 become R 11 YO, R 11 YNZ 1 , and R 11 YCZ 2 Z 3 , respectively, an alkyl, alkenyl, aryl, arylalkyl, alkylaryl, arylalkenyl, alkenylaryl having from 1 to 18 carbon atoms and optionally substituted by one or more oxa, thia or aza; a dialkylamino group N(R 11 ) 2 ; Z 1 , Z 2 , and Z 3 represent independently R 11 , R 11 YO or CN, this group being optionally part of a polymeric chain.
