SINGLE OR MULTI-NUCLEAR METAL COMPLEXES AND THEIR USE AS BLEACHING AND OXIDATION CATALYSTS

摘要

Single or multi-nuclear metal complexes [LnMmXp]Y, in which M is manganese in the oxidation number (II, III, IV, V and/or VI), copper in the oxidation number (I and/or II), cobalt in the oxidation number (II and/or III) or zinc in the oxidation number (II), X is a co-ordination or bridge group, Y is a counter-ion in the corresponding stoichiometric quantity for compensating a charge z, in which z may be positive, zero or negative as the charge of the metal complex, n and m are mutually independently whole numbers from 1 to 8, p is a whole number from 0 to 32 and L is certain nitrogen and/or oxygen atoms as co-ordination centres-containing organic molecules as ligands. The metal complexes (I) are suitable as bleaching and oxidation catalysts, especially in washing and cleaning agents and in textile and paper bleaching.
