ARYL-SUBSTITUTED BICYCLIC COMPOUNDS AS HERBICIDES Russian patent published in 2021 - IPC C07D487/04 A01N43/653 A01N43/52 A01N43/56 A01P13/00 

FIELD: organic chemistry.

SUBSTANCE: invention relates to a compound of Formula 1, in which Q¹ is a phenyl ring substituted with no more than 5 substituents, independently selected from R⁹; Q² is a phenyl ring substituted with no more than 5 substituents, independently selected from R¹¹; each of R¹ and R² independently represents H; Y is O; A is a saturated, partially unsaturated, or completely unsaturated chain containing 2-4 atoms selected from no more than 4 carbon atoms and no more than 1 N atom, while no more than 1 carbon link is independently selected from C(=O); the specified chain is optionally replaced by no more than 1 substituent, independently selected from R³ at carbon atoms; each R³ independently represents C₁-C₄ alkyl; J is -CR⁵R⁶-; each of R⁵ and R⁶ independently represents H; R⁷ is H; each of R⁹ independently represents halogen, C₁-C₈ alkyl or C₁-C₈ haloalkyl; and each of R¹¹ independently represents halogen, C₁-C₈ alkyl, C₁-C₈ haloalkyl or C₁-C₈ alkyltio; provided that when Q¹ is 3-trifluoromethylphenyl and Q² is 2-fluorophenyl, A is not -CH₂CH₂-. The invention also relates to a herbicide composition based on the specified compound.

EFFECT: new compounds and a composition based on them have been obtained, which can be used in agriculture to control the growth of weeds.
