主权项 1. A uronium salt of formula (1) in which X denotes O, R and R0 each, independently of one another, have the meaning of straight-chain or branched alkyl having 1-20 C atoms, straight-chain or branched alkenyl having 2-20 C atoms and one or more double bonds, straight-chain or branched alkynyl having 2-20 C atoms and one or more triple bonds saturated, partially or fully unsaturated cycloalkyl having 3-7 C atoms, which are optionally substituted by one or more alkyl groups having 1-6 C atoms, and R may also denote hydrogen, where one or more R or R0 are optionally partially or fully substituted by halogen or partially by CN or NO2, but where halogenation in the α-position in R0 is excluded, and halogen denotes F, Cl, Br or I, where R and R0 may be connected to one another in pairs by a single or double bond and where one carbon atom or two non-adjacent carbon atoms of one or more R or R0 which are not directly adjacent to the hetero atom may be replaced by atoms and/or atom groups selected from the group consisting of —O—, —C(O)—, —C(O)O—, —S—, —S(O)—, —SO2—, —SO3—, —N═, —N═N—, —NH—, —NR′—, —PR′—, —P(O)R′—, —P(O)R′—O—, —O—P(O)R′—O—, and —P(R′)2═N—, where R′ is unfluorinated, partially or perfluorinated alkyl having 1-6 C atoms, saturated or partially unsaturated cycloalkyl having 3-7 C atoms, unsubstituted or substituted phenyl or an unsubstituted or substituted heterocycle, A− is selected from the group consisting of: [R1SO3]−, [RF′SO3]−, [(RFSO2)2N]−, [(RFSO2)3C]−, [(FSO2)3C]−, [R1CH2OSO3]−, [R1C(O)O]−, [RF′C(O)O]−, [CCl3C(O)O]−, [(CN)3C]−, [(CN)2CR1]−, [(R1O(O)C)2CR1]−, [P(CnF2n+1−mHm)yF6−y]−, [P(C6F5)yF6−y]−, [R12P(O)O]−, [R1P(O)O2]O2−, [(R1O)2P(O)O]−, [(R1O)P(O)O2]2−, [(R1O)(R1)P(O)O]−, [RF2P(O)O]−, [RFP(O)O2]2−, [BFzRF4−z]−, [BFz(CN)4−z]−, [B(CN)4]−, [B(C6F5)4]−, [B(OR1)4]−, [N(CF3)2]−, [N(CN)2]−, [AlCl4]− and [SiF6]2−, where RF and RF′ each, independently of one another, the meaning of perfluorinated and straight-chain or branched alkyl having 1-20 C atoms, where the trifluoromethyl group is excluded for RF′, perfluorinated and straight-chain or branched alkenyl having 2-20 C atoms and one or more double bonds, perfluorinated phenyl and saturated, partially or fully unsaturated cycloalkyl having 3-7 C atoms, which is optionally substituted by perfluoroalkyl groups, where the RF or RF′ are optionally connected to one another in pairs by a single or double bond and where one carbon atom or two non-adjacent carbon atoms of RF or RF′ which are not in the α-position to the hetero atom are optionally replaced by atoms and/or atom groups selected from the group consisting of —O—, —C(O)—, —S—, —S(O)—, —SO2—, —N═, —N═N—, —NR′—, —PR′— and —P(O)R′— or optionally have an end group R′—O—SO2— or R′—O—C(O)—, where R′ denotes unfluorinated, partially or perfluorinated alkyl having 1-6 C atoms, saturated or partially unsaturated cycloalkyl having 3-7 C atoms, unsubstituted or substituted phenyl or an unsubstituted or substituted heterocycle and where R1 each, independently of one another, have the meaning of hydrogen in the case where A−=[(CN)2CR1]− or [(R1O(O)C)2CR1]−, or hydrogen in the case where A−=[R1CH2OSO3]−, and R and R0=alkyl groups having 1 to 20 C atoms, straight-chain or branched alkyl having 1-20 C atoms, straight-chain or branched alkenyl having 2-20 C atoms and one or more double bonds, straight-chain or branched alkynyl having 2-20 C atoms and one or more triple bonds, saturated, partially or fully unsaturated cycloalkyl having 3-7 C atoms, which is optionally substituted by alkyl groups having 1-6 C atoms, where R1 is optionally partially substituted by CN, NO2 or halogen and halogen denotes F, Cl, Br or I, where R1 is optionally connected to one another in pairs by a single or double bond and where one carbon atom or two non-adjacent carbon atoms of R1 which are not in the α-position to the hetero atom are optionally replaced by atoms and/or atom groups selected from the group consisting of —O—, —C(O)—, —C(O)O—, —S—, —S(O)—, —SO2—, —SO3—, —N═, —N═N—, —NH—, —NR′—, —PR′— and —P(O)R′—, (P(O)R′O—, OP(O)R′O—, —PR′2═N—, —C(O)NH—, —C(O)NR′—, —SO2NH— and —SO2NR′—, where R′ denotes unfluorinated, partially or perfluorinated alkyl having 1-6 C atoms, saturated or partially unsaturated cycloalkyl having 3-7 C atoms, unsubstituted or substituted phenyl or an unsubstituted or substituted heterocycle and n denotes 1 to 20, m denotes 0, 1, 2 or 3, y denotes 0, 1, 2, 3, or 4, and z denotes 0, 1, 2 or 3, with the proviso that the anions A−=CF3COO− and [B(C6H5)4]− are to be allowed and R0=ethyl, the anion A−=CH3CH2OSO3− is to be excluded.
