Abstract RU 2652132 C2

FIELD: agriculture.

SUBSTANCE: invention refers to agriculture. Compound of formula (I):

in which X is CY; where Y is hydrogen, halogen, C1-C3-alkyl, C1-C3-haloalkyl, C1-C3-alkoxy, C1-C3-haloalkoxy, C1-C3-alkylthio or C1-C3-haloalkylthio; R1 means OR1', in which R1' means H, C1-C8-alkyl or C7-C10-aryl alkyl; R2 means a halogen selected from F, Cl or Br, C1-C4-alkyl, C1-C4-haloalkyl, C2-C4-alkenyl, C2-C4-haloalkenyl, C2-C4-alkynyl, C2-C4-haloalkynyl, C1-C4-alkoxy, C1-C4-haloalkoxy, C1-C4-alkylthio, C1-C4-haloalkylthio, amino, C1-C4-alkylamino, C2-C4-haloalkylamino, formyl, (C1-C3-alkyl) carbonyl, (C1-C3-haloalkyl) carbonyl or cyano, provided that R2 is not SCH3; R3 and R4 each independently is hydrogen, C1-C6-alkyl, C1-C6-haloalkyl, C3-C6-alkenyl, C3-C6-haloalkenyl, C3-C6-alkynyl, hydroxy, C1-C6-alkoxy, C1-C6-haloalkoxy, formyl, (C1-C3-alkyl) carbonyl, (C1-C3-haloalkyl)carbonyl, (C1-C6-alkoxy) carbonyl, (C1-C6-alkyl) carbamyl, C1-C6-alkylsulfonyl, tri (C1-C6-alkyl) silyl or di (C1-C6-alkyl) phosphonyl, or R3 and R4 together with the nitrogen atom, to which they are attached, form a 5- or 6-membered saturated ring, or R3 and R4, taken together, mean = CR3'R4', where R3' and R4' each independently is hydrogen, C1-C6-alkyl, C3-C6-alkenyl, C3-C6-alkynyl, C1-C6-alkoxy or C1-C6-alkylamino, or R3' and R4' together with the carbon atom to which they are attached, form a 5- or 6-membered saturated ring; Ar is Ar2, Ar3, Ar4, Ar5 or Ar6.
