Description

The description relates to novel sulphonium salts of general formula (I) in which A is a monovalent radical of general formula (II), G is a monovalent aromatic hydrocarbon radical with 6 to 14 carbon atoms or a monovalent aromatic hydrocarbon radical with 5 to 14 ring atoms containing at least one oxygen and/or sulphur atom, with the proviso that in the radical G one hydrogen atom is replaced by a chemical bond to the sulphur atom and D, E and F are constituents of G, where D is a radical of formula: -(O)x-(R)y-SiR31, E is a radical of the formula -OR2, F is a radical of the formula -R3, a is 1, 2 or 3, b is 0, 1 or 2, c is 0, 1 or 2, x is 0 or 1 and y is 0 or 1, and R, R1, R2 and R3 have the meanings given in Claim 1, X- is a halide ion, Z- is a tosylate anion or a weakly or non-nucleophilic anion, Y- is selected from the group CF3CO2-, BF4, PF6-, AsF6-, SbF6-, ClO4-, HSO4- and CnF(2n+1-m)Hm-SO3-, where n and m have the meanings given in Claim 1.
