    Abstract: PCT No. PCT/EP90/01897 Sec. 371 Date Mar. 3, 1992 Sec. 102(e) Date Mar. 3, 1992 PCT Filed Nov. 13, 1990 PCT Pub. No. WO91/08279 PCT Pub. Date Jun. 13, 1991.Heterocyclic compounds which are useful as bleach activators or optical brighteners in washing and cleaning agents have the formula (* CHEMICAL STRUCTURE *) I where the variables have the following meanings: X is O, S or the group N-R3, where R3 is hydrogen, C1-C25-alkyll C1-C25-acyl or an aryl group of up to 12 carbon atoms, Y is CH or N, R1 for X=S or N-R3 is hydrogen, a C1-C25-alkyl or C2-C25-alkenyl group or a phenyl radical which may be additionally substituted by one or two C1-C4-alkyl, C1-C4-alkoxy, hydroxyl, carboxyl, sulfo, amino, C1-C4-acylamino, nitro or cyano groups or chlorine or bromine atoms, which substituents, if there are two of them, may be identical or different, R1 for X=O is phenyl, o-, m- or p-tolyl, p-chlorophenyl, m-nitrophenyl, m-methoxyphenyl or m-methylsulfonylphenyl, R2 for X=S or N-R3 is hydrogen, a C1-C4-alkyl, C1-C4-alkoxy, hydroxyl, carboxyl, sulfo, amino or C1-C4-acylamino group or a chlorine or bromine atom, and R2 for X=O is hydrogen.
