NOVEL 1-ARYL-4-THIOURACILS

摘要

The invention relates to novel 1-aryl-4-thiouracils of formula (I), to their salts/enolethers used as herbicides, whereby R1 = H, NH¿2?, C1-C6-alkyl; R?2¿ = H, halogen, C¿1?-C4-alkyl, C1-C4-alkyl halide; R?3¿ = H, halogen, C¿1?-C6-alkyl, methyl halide; R?4¿ = H, halogen; R5 = CN, halogen, -CO-NH¿2?, -CS-NH2, -OC(R?8,R9¿)-CO-O(C¿1?-C6-alkyl); Y = N, CH, or together with R?6¿, a bridge ⊃C-O-C(R?10)=N-; R6¿, together with R5, = a radical -N(R7)-C(O/S)-C(R8',R9')-O- bound to R5 via the oxygen, or 1) H, OH, SH, CN, NO¿2?, halogen, C1-C6-alkyl, C1-C6-alkyl halide, C1-C6-alkoxy halide, C1-C6-alkylthio halide, C1-C6-alkylthio-(C1-C6-alkyl)carbonyl, (C1-C6-alkyl)imino-oxycarbonyl, C1-C6-alkoxy-C1-C6-alkyl, C1-C6-alkoxyamino-C1-C6-alkyl, C1-C6-alkoxy-C1-C6-alkylamino-C1-C6-alkyl, 2) optionally substituted C1-C6-alkoxy, C1-C6-alkylthio, C3-C6-cycloalkoxy, C3-C6-cycloalkylthio, C2-C6-alkenyloxy, C2-C6-alkenylthio, C2-C6-alkynyloxy, C2-C6-alkynylthio, (C1-C6-alkyl)carbonyloxy, (C1-C6-alkyl)carbonylthio, (C1-C6-alkoxy)carbonyloxy, (C2-C6-alkenyl)carbonyloxy, (C2-C6-alkenyl)carbonylthio, (C2-C6-alkynyl)carbonyloxy, (C2-C6-alkynyl)carbonylthio, C1-C6-alkylsulfonyloxy or C1-C6-alkylsulfonyl, 3) 28 additional radicals; R?7¿ = H, optionally substituted C¿1?-C6-alkyl, C3-C6-alkenyl, C3-C6-alkynyl, C1-C6-alkoxy, C3-C6-alkenyloxy, C3-C6-alkynyloxy, C3-C6-cycloalkyl or C3-C6-cycloalkoxy; R?8, R9, R8', R9'¿ = H, CN, C¿1?-C6-alkyl; R?10¿ = H, halogen, optionally substituted C¿1?-C6-alkyl, C3-C6-alkenyl, C3-C6-alkynyl, C1-C6-alkoxy, C3-C6-alkenyloxy, C3-C6-alkynyloxy, C3-C6-cycloalkyl or C3-C6-cycloalkoxy.
