CA 2125774

The invention concerns iodinium salts of the general formula A-J+-B X-, in which A is a group of the general formula (1) in which C is a monovalent aromatic hydrocarbon group with 6 to 14 carbon atoms or a monovalent aromatic hydrocarbon group containing at least one oxygen and/or sulphur atom and with 5 to 14 atoms in the aromatic ring, D, E and F are each substituents of C, D being a group of the formula -(0)x-(R)y-SiR1/3, E being a group of the formula -OR2, F being a group of the formula -R3, a being 1, 2, or 3, b being 0, 1 or 2, c being 0, 1 or 2, x being 0 or 1 and y being 0 or 1, and R, R1, R2 and R3 are as defined in claim 1; B is a group of the formula (2) in which E and F, which are as defined above, may each be bound to the 2, 3, 4, 5 or 6 position in the benzene ring, d is 0, 1 or 2, e is 0, 1 or 2 and X- is a tosylate anion or a weakly nucleophilic or non-nucleophilic anion Y- selected from the group comprising CF3C02-, BF4-, PF6-, AsF6; SbF6-, C104-, H304- and CF3S03-.

Sels d'iodinium de formule générale A-J+-B X-, où A est un groupe de formule générale (1), où C est un groupe hydrocarboné aromatique monovalent de 6 à 14 atomes de carbone ou un groupe hydrocarboné aromatique monovalent renfermant au moins un atome d'oxygène et (ou) un atome de soufre, avec 5 à 15 atomes de carbone dans le cycle aromatique, D, E et F sont tous des substituants de C, D est un groupe de formule -(0)x-(R)y-SiR1/3, E est un groupe de formule -OR2, F est un groupe de formule -R3, a est 1, 2, ou 3, b est 0, 1 ou 2, c est 0, 1 ou 2, x est 0 ou 1 et y est 0 ou 1, R, R1, R2 et R3 sont définis dans la revendication 1; B est un groupe de formule (2) où E et F, définis ci-dessus, peuvent être liés en position 2, 3, 4, 5 ou 6 au noyau benzénique, d est 0, 1 ou 2, e est 0, 1 ou 2 et X- est un anion de tosylate ou un anion nucléophile faible ou non nucléophile, Y- est sélectionné dans le groupe comprenant CF3C02-, BF4-, PF6-, AsF6; SbF6-, C104-, H304- et CF3S03-.
