Abstract

Described are complexes of the transition metals manganese, iron, cobalt, ruthenium, molybdenum, titanium, vanadium and/or copper containing one or more ligands of general formula (I) ou (II) in which R is a direct bond or an optionally amin-group-substituted alkylene group with 1 to 4 C-atoms, A is a condensed or non-condensed ring system containing at least one nitrogen atom, B is hydrogen, an OH-group or the same as A, and X is a phenyl ring optionally substituted with and/or C.sub.1-4 alkyl or an optionally hydroxy-substituted C.sub.1-4 alkylene group. The complexes are suitable for use as activators or peroxy compounds in oxidative washing, cleaning and disinfectant solutions, washing and cleaning agents preferably containing 0.0025 to 0.25% by wt. of such activator complexes. ##STR1##
