Claim 13:
14. The process according to claim 12 wherein the n-valent anion An− is independently selected from halide, tetrafluoroborate (BF4−), tetrakis[3,5-bis(trifluoromethyl)phenyl]borate ([{3,5-(CF3)2C6H3}4B]−), perchlorate (ClO4−), hexafluorophosphate (PF6−), antimony hexafluoride (SbF6−), nitrate (NO3−), a sulfonate anion of the formula R12SO3 wherein R12 is selected from C1-C4-alkyl, C1-C4-haloalkyl and unsubstituted or substituted C6-C20-aryl, a carboxylate ion of the formula R13COO− wherein R13 is selected from hydrogen, C1-C8-alkyl, C3-C12-cycloalkyl, C1-C8-haloalkyl and unsubstituted or substituted C6-C20-aryl, sulfate (SO42−), and a bis(sulfonyl)imide anion of the formula (R14SO2)2N−, wherein R14 is selected from C1-C4-alkyl, C1-C4-haloalkyl and unsubstituted or substituted C6-C20-aryl.
