Abstract:
1. A 4-phenylpyridazinone of formula (I) or a salt thereof in which A and B are in each case independently of one another hydrogen or (C G is hydrogen, C(═O)R E is a metal ion equivalent or an ammonium ion; L is oxygen or sulfur; M is oxygen or sulfur; R R or is (C 3 -C 6 )-cycloalkyl, phenyl or benzyl, each of which is substituted by n radicals selected from the group consisting of halogen, (C 1 -C 4 )-alkyl and (C 1 -C 4 )-alkoxy; R or phenyl, benzyl, phenoxy or phenylthio which is substituted by n radicals selected from the group consisting of halogen, (C 1 -C 4 )-alkyl and (C 1 -C 4 )-alkoxy; R (C 1 -C 6 )-alkyl which is substituted by n halogen atoms, (C 3 -C 6 )-cycloalkyl, (C 2 -C 6 )-alkenyl, (C 1 -C 6 )-alkoxy or (C 1 -C 4 )-alkoxy-(C 1 -C 6 )-alkyl, phenyl or benzyl, each of which is substituted by n radicals selected from the group consisting of halogen, (C 1 -C 4 )-alkyl and (C 1 -C 4 )-alkoxy; or R 6 and R 7 together with the nitrogen atom to which they are attached form a 3- to 6-membered ring which contains 2 to 5 carbon atoms and 0 or 1 oxygen or sulfur atoms; m is 1, 2 or 3; n is 0, 1, 2 or 3; X is halogen, cyano, (C Y and Z are each independently of one another hydrogen, halogen, cyano, nitro, (C with the proviso that neither Y nor Z is a (C 1 -C 6 )-alkyl or (C 1 -C 6 )-alkoxy radical located in position 6 if n is 0; with the proviso that the compound is not: 4(2,4-dichlorophenyl)-5-hydroxy-2-methylpyridazin-3(2H)-one.
