ARYLALKYL ESTERS OF 4-AMINO-6-(SUBSTITUTED PHENYL)PICOLINATES AND 6-AMINO-2-(SUBSTITUTED PHENYL)-4-PYRIMIDINE CARBOXYLATES AND USE THEREOF AS HERBICIDES Russian patent published in 2015 - IPC C07D239/42 C07D239/30 A01N43/54 A01P13/00 

FIELD: chemistry.

SUBSTANCE: invention relates to novel arylalkyl esters of 4-aminopicolinic acids of formula IB, having herbicidal activity, and can be used for weed control. In formula IB: X is H or F; Y is phenyl, substituted with 1-4 substitutes independently selected from halogen, C₃-C₆cycloalkyl, C₁-C₃alkoxy, C₁-C₃haloalkyl, C₁-C₃haloalkoxy; Z is halogen; R¹ and R² is H; R³ is an arylalkyl, selected from naphthyl-(C_1-2)alkyl or phenyl-(C_1-2)alkyl, which can be unsubstituted or substituted with 1-2 substitutes, independently selected from halogen, nitro, cyano, C₁-C₆alkyl, C₁-C₆alkoxy, halogenated C₁-C₆alkyl, halogenated C₁-C₆alkoxy, C₁-C₆alkylthio, C(O)OC₁-C₆alkyl, or where two adjacent substitutes taken together are -O(CH₂)_nO- or -O(CH₂)_n-, where n=1 or 2.

EFFECT: compounds have selective action and are particularly applicable, at the post-germination phase, to control types which are usually encountered in systems for growing rice, wheat or fodder plants.
