Disubstituted thiazolyl carboxanilides and their use as microbicides
View Patent ↗The present invention relates to novel thiazolylcarboxanilides of formula (I) in which R 1 and R 2 are as defined in the disclosure, to a plurality of processes for preparing these substances and their use for controlling unwanted microorganisms, and further relates to novel intermediates of their preparation.
1. A thiazolylcarboxanilide of formula (I)
in which
R 1 and R 2 independently of one another represent halogen, cyano, nitro, C 1 –C 6 -alkyl, C 2 –C 6 -alkenyl, C 1 –C 4 -alkoxy, C 1 –C 4 -alkylthio, C 1 –C 4 -alkylsulphonyl, or C 3 –C 6 -cycloalkyl; or represent C 1 –C 4 -haloalkyl, C 1 –C 4 -haloalkoxy, C 1 –C 4 -haloalkylthio, or C 1 –C 4 -haloalkylsulphonyl having in each case 1 to 5 halogen atoms,
or if R 1 and R 2 are arranged ortho to each other, then R 1 and R 2 together optionally also represent optionally halogen- or C 1 –C 6 -alkyl-substituted alkenylene.
2. A thiazolylcarboxanilide of formula (I) according to claim 1 in which
R 1 and R 2 independently of one another represent fluorine, chlorine, bromine, cyano, nitro, methyl, ethyl, n- or i-propyl, n-, i-, s-, or t-butyl, methoxy, ethoxy, methyl-thio, ethylthio, n- or i-propylthio, cyclopropyl, trifluoromethyl, trichloromethyl, trifluoroethyl, difluoromethoxy, trifluoromethoxy, difluorochloromethoxy, trifluoroethoxy, difluoromethylthio, difluorochloromethylthio, or trifluoro-methylthio,
or if R 1 and R 2 are arranged ortho to each other, then R 1 and R 2 together optionally also represent optionally fluorine-, chlorine-, bromine-, or methyl-substituted butadienylene.
3. A thiazolylcarboxanilide of formula (I) according to claim 1 in which R 1 and R 2 independently of one another represent fluorine, chlorine, bromine, methyl, trifluoromethyl, difluoromethoxy. or trifluoromethoxy.
4. A thiazolylcarboxanilide of formula (I) according to claim 1 in which R 1 represents fluorine and R 2 represents chlorine.
5. A thiazolylcarboxanilide of formula (I) according to claim 1 in which R 1 represents fluorine and R 2 represents fluorine.
6. A thiazolylcarboxanilide of formula (I) according to claim 1 in which R 1 represents methyl or trifluoromethyl.
7. A composition for controlling unwanted microorganisms comprising one or more thiazolylcarboxanilides of formula (I) according to claim 1 and one or more extenders and/or surfactants.
8. A method for controlling unwanted microorganisms comprising applying an effective amount of a thiazolylcarboxanilide of formula (I) according to claim 1 to the microorganisms and/or their habitat.
