    Abstract: Bleach systems contain bis- and tris-( mu -oxo)-di-manganese complex salts of formula (I) ÄLMn( mu -O)a( mu -OAc)bMnLÜ (x+) Ay; in which Ac = 2-8C acyl; a = 1-3; b = 0 if a = 2 or 3 or b = 2 if a = 1; x = 2 or 3; A = a mono- or di-valent anion; y = the equivalent amount of anion A to balance the positive charges; L = a ligand of formula R-N(Q)2 (II) or (Q)2N-(C(R )2)g-N(Q)2 (III); Q = a group of formula (i); R = 1-12C alkyl, 5-10C cycloalkyl, phenyl, NH2, NHR , N(R )2, OH, OR or COOH; R = H, 1-12C alkyl, 5-10C cycloalkyl, NH2, NHR , N(R )2, OH, OR , COOH, COOR , Cl, Br, F or CN; R = 1-12C alkyl or 5-10C cycloalkyl; g = 2 or 3; m, n = 0-4. Also claimed are washing agents and cleaning agents containing this bleach system.

    Abstract: A process for the preparation of ureidoperoxycarboxylic acids of the formula A[NHCONHBCOOOH]x, in which x is the number 1 or 2, A, if x is 1, is hydrogen, C1-C20-alkyl, aryl, preferably phenyl, or haloaryl, preferably chlorophenyl, or if x is 2, is C1-C20-alkylene or arylene, preferably phenylene, B is a group of the formula in which n is a number from 1 to 20, m is the number 0, 1 or 2, R1 is C1-C20-alkyl and R2 is in each case hydrogen or C1-C20-alkyl, which comprises dissolving carbamoyllactams of the formula in which x, A and B have the abovementioned meanings, in a one- to six-fold, preferably a one- to three-fold, amount by weight of a strong catalyst acid, by then adding water in a one- to ten-fold molar excess, relative to the carbamoyllactam, to the solution of the carbamoyllactam in the catalyst acid and by heating the reaction mixture to form the ureidocarboxylic acid, by then adding to the reaction mixture an aqueous hydrogen peroxide solution in a one- to ten-fold, preferably a two- to four fold, molar excess per oxidizable carboxyl group of the ureidocarboxylic acid formed in the preceding reaction step, and by then precipitating the resulting ureidoperoxycarboxylic acid from the reaction mixture. These compounds are suitable as bleaches, oxidants and disinfectants.
