Use is claimed of nitrogen ligand-containing transition metal complexes as catalysts for peroxy compounds. Use is claimed of nitrogen ligand-containing transition metal complexes of formula (I) as catalysts for peroxy compounds. M(L)nXm (I) M : Mn, Fe, Co, Ni, Mo or W; L : a nitrogen-containing heterocyclic ligand; X = chloride, bromide, nitrate, perchlorate, sulfate, ammonia, tetrafluoroborate, hexafluorophosphate or an anion of a 1-22C organic acid; n : integer 2-4; and m : integer 0-4. Independent claims are also included for detergent, bleaching and cleansing agents containing (I). Beansprucht wird die Verwendung von Verbindungen der Formel (1) M(L)nXm wobei M: ein Metallatom aus der Gruppe Mn, Fe, Co, Ni, Mo, W, L: ein Ligand aus der Gruppe der stickstoffhaltigen Heterocyclen, X: Chlorid, Bromid, Nitrat, Perchlorat, Sulfat, Ammoniak, Tetrafluoroborat, Hexafluorophosphat oder ein Anion einer organischen Säuren mit 1 bis 22 Kohlenstoffatomen, n: eine Zahl von 2 bis 4 und m eine Zahl von 0 bis 4 bedeuten, als Katalysator für Persauerstoffverbindungen, insbesondere in Wasch-, Bleich- und Reinigungsmitteln.
