QUINAZOLINE(DI)ONES, COMPOSITION FOR CONTROL OF INSECT-PESTS, METHOD FOR CONTROL OF INSECT-PESTS, INTERMEDIATE COMPOUND Russian patent published in 2008 - IPC C07D401/14 A01N43/54 A01P7/04 C07C237/20 

FIELD: organic chemistry, insecticides.

SUBSTANCE: invention describes compounds of the formula (1) wherein A and B mean oxygen atom (O); J means pyrazole ring; K in common with two adjacent binding carbon atoms represents phenyl ring substituted with from 1 to 2 substitutes chosen independently from R⁴; L means a binding chain comprising from 1 to 2 members chosen from carbon atom and optionally substituted with one R¹³; or L means C(=E) wherein E means O; R³ means hydrogen atom (H) or (C₁-C₆)-alkyl; each R⁴ means independently (C₁-C₆)-alkyl, halogen atom or -CN; each R⁵ means independently (C₁-C₆)-halogenalkyl, halogen atom or (C₁-C₄)-halogenalkoxy-group; or each R⁵ means independently phenyl or pyridyl ring wherein each ring is substituted with R⁶; each R⁶ means halogen atom; each R¹³ means independently -COOH, (C₂-C₆)-alkoxycarbonyl or (C₂-C₆)-alkoxycarbonylalkyl; or each R¹³ means phenyl substituted with (C₂-C₆)-alkoxycarbonyl; pyridinyl or imidazole ring; n = 1 or 2. Proposed compounds show insecticide activity. Also, invention describes a composition used for control of insect-pests and a method for control of insect-pests, and compounds of the formula (6) wherein R³ means H or (C₁-C₄)-alkyl, one R⁴ is added to phenyl ring at position 2 and means CH₃ or halogen atom, and the second R⁴ means optionally F, Cl, Br, J or -CN.

EFFECT: valuable properties of compounds and composition.
