| abstract |
The invention relates to novel 1-aryl-4-thiotriazines of formula (I), wherein R<1> = H, NH2, C1-C4-alkyl, C1-C4-alkyl halide; R<2> = H, NH2, C1-C4-alkyl, C1-C4-alkyl halide; R<3> = H, halogen; R<4> = CN, halogen; Y = nitrogen, the methine group or together with R<5>, a bridge >C-O-C(R<6>)=N-; R<5> = 1) hydrogen, hydroxy, mercapto, nitro, halogen, C1-C6-alkyl, C1-C6-alkyl halide, 2) C1-C6-alkoxy, C1-C6-alkylthio, C3-C6-cycloalkoxy, C3-C6-cycloalkylthio, C2-C6-alkenyloxy, C2-C6-alkenylthio, C2-C6-alkinyloxy or C2-C6-alkinylthio, each of these 8 radicals optionally bearing one of the following substituents: halogen, cyano, -CO-R<8>, -CO-OR<8> or -CO-N(R<8>)-R<9>; 3) -CO-R<11>, -C(R<11>)(OR<13>)(OR<14>), -C(R<11>)=C(R<15>)-CO-R<16>, -CH(R<11>)-CH(R<15>)-CO-R<16>, -CO-OR<20>, -C(R<10>)=N-OR<7>, -N(R<21>)-R<22> or -CO-N(R<21>)-R<22>; and R<6> = H, halogen, optionally substituted C1-C6-alkyl, C3-C6-alkenyl, C3-C6-alkinyl, C1-C6-alkoxy, C3-C6-alkenyloxy, C3-C6-alkinyloxy, C3-C6-cycloalkyl or C3-C6-cycloalkoxy. The invention also relates to salts and enol ethers of the inventive compounds (I), to a method for producing them and to their use as herbicides. |
