Patent

CA 2407939

Compounds are provided that may be used as ligands in transition metal complexes, in turn useful as bleach catalysts. Also provided are complexes, bleaching compositions and methods using the compounds. The compounds are of the general formula: wherein Z represents a group selected from -NH-2, -NHR4, - N(R4)2, -N(R4)3+, -NO2, -NHC(O)R4, -N(R4)C(O)R4 (wherein R4 represents alkyl, cycloalkyl, aryl, arylalkyl or heteroarylalkyl, each optionally substituted by -F, -Cl, -Br, -I, -NH3+, -SO3H, -SO3-(Na+, K+), -COOH, -COO-(Na+, K+), - P(O)(OH)2, or -P(O)(O-(Na+, K+))2 ), an optionally substituted heterocyclic ring or an optionally substituted heteroaromatic ring selected from pyridine, pyrimidine, pyrazine, pyrazole, imidazole, benzimidazole, quinoline, quinoxaline, triazole, isoquinoline, carbazole, indole, isoindole, oxazole and thiazole.

L'invention concerne des composés que l'on peut utiliser en tant que ligands dans des complexes de métaux de transition, utiles à leur tour en tant que catalyseurs de blanchiment. L'invention concerne également des complexes, compositions de blanchiment, et procédés d'utilisation de ces composés, lesquels correspondent à la formule générale (I) dans laquelle Z représente un groupe choisi dans le groupe constitué par -NH-¿2?, -NHR?4¿, -N(R?4¿)¿2?, -N(R?4¿)¿3??+¿, -NO¿2?, -NHC(O)R?4¿, -N(R?4¿)C(O)R?4¿ (où R?4¿ représente alkyle, cycloalkyle, aryle, arylalkyle ou héteroarylalkyle, chacun étant éventuellement substitué par -F, -Cl, -Br, -I, -NH¿3??+¿, -SO¿3?H, -SO¿3??-¿(Na?+¿, K?+¿), -COOH, -COO?-¿(Na?+¿, K?+¿), -P(O)(OH)¿2?, ou -P(O)(O?-¿(Na?+¿, K?+¿))¿2? ), un noyau hétérocyclique éventuellement substitué, ou un noyau hétéroaromatique éventuellement substitué, choisi dans le groupe constitué par pyridine, pyrimidine, pyrazine, pyrazole, imidazole, benzimidazole, quinoline, quinoxaline, triazole, isoquinoline, carbazole, indole, iso-indole, oxazole et thiazole.
