CA 2671082

The invention relates to all compounds of the formula (I) or (II) in which: L is a neutral ligand; X, X' are anionic ligands; R1 and R2 are, separately, a hydrogen, a C1-C6 alkyl, a C1-C6 perhalogenoalkyl, a aldehyde, a ketone, an ester, a nitrile, an aryl, a pyridinium alkyl, an optionally substituted C5 or C6 pyridinium alkyl, perhalogenoalkyl or cyclohexyl, a CnH2nY or CnF2nY radical 10 with n between 1 and 6 and y an ionic marker, or a radical having the formula: wherein R1 can be a radical of formula (Ibis) when the compound has formula (I) or of formula (IIbis) when the compound has formula (II), R3 is a C1-C6 alkyl, or a C5 or C6 cycloalkyl or a C5 or C6 aryl; R0, R4, R5, R6, R7, R8, R9, R10, R11 are, separately, a hydrogen, C1-C6alkyl, a C1-C6 perhalogenoalkyl, or a C5 or C6 aryl; wherein R9, R10, R11 can be a heterocycle; X1 is an anion. R1 and R2 can form, with the N and the C to which they are attached, a heterocycle.

L'invention concerne tout composés de formule (I) ou (II) dans laquelle: L est un ligand neutre; X, X' sont des ligands anioniques; R1 et R2 sont, indépendamment, un hydrogène, un alkyl en C1 à C6, un perhalogénoalkyl en C1 à C6, un aldéhyde, une cétone, un ester, un nitrile, un aryl, un pyridinium-alkyl, un pyridinium- perhalogénoalkyl- ou un cyclohexyl en C5 ou C6 éventuellement substitué, un radical 10 CnH2nY ou CnF2nY avec n compris entre 1 et 6 et Y un marqueur ionique, ou un radical de formule : R1 pouvant être un radical de formule (Ibis) quand le composé est de formule (I) ou de formule (IIbis) quand le composé est de formule (II) R3 est un alkyl en C1 à C6, ou un cycloalkyl en C5 ou C6 ou un aryl en C5 ou C6; R0, R4, R5, R6, R7, R8, R9, R10, R11 sont, indépendamment, un hydrogène, un alkyl en C1 à C6, un perhalogénoalkyl en C1 à C6, ou un aryl en C5 ou C6; R9, R10, R11 pouvant former un hétérocycle; X1 est un anion. R1 et R2 pouvant former avec le N et le C auxquels ils sont rattachés un hétérocycle.
