Transition metal complexes of formula M(L)x(A)y (I) are used as activators for peroxy cpds. in oxidising, washing, cleaning or disinfecting solns. M = Mn, Fe, Co, Ro or Mo; x = 1-3; A = a charge-equalising anion ligand; y = 0-4; L = an organic ligand of formula (II): X = H, R3, OR3, NO2, ONO, F, Cl, Br or iodine; R1, R2, R3 = H, alkyl, alkenyl, benzyl, Ph or a cycloalkyl gp., which is opt. alkyl- and/or aryl-substd., with a total of 1-12C; m, n = 0 or 1. |
