SUBSTITUTED DIHYDRO-3-HALOGEN-1H-PYRAZOL-5-CARBOXYLATES, THEIR PREPARING AND USING Russian patent published in 2008 - IPC C07D231/06 C07D231/08 C07D231/16 C07D401/04 A01N43/56

Abstract RU 2317983 C2

FIELD: organic chemistry, chemical technology.

SUBSTANCE: invention relates to novel compounds of the formula (I): wherein R¹ represents halogen atom; R² represents halogen atom; R³ represents (C₁-C₄)-alkyl; X represents nitrogen atom (N) or -CH; n = 0-3 under condition that when X represents -CH then n= 1 at least. Also, invention relates to novel compounds of the formula (II): wherein R¹ represents halogen atom; R² represents halogen atom; R³ represents hydrogen atom (H) or (C₁-C₄)-alkyl; X represents N or -CH; n = 0-3 under condition that when X represents -CH then n = 1 at least. Also, invention relates to a method for synthesis of compound of the formula (I), a method for synthesis of compound of the formula (II) and to a method for synthesis of compound of the formula (III) given in the invention description. Also, invention describes intermediate compounds of the formula (4) given in the invention description. Invention provides synthesis of novel biologically active compounds that can be used as insecticides, and a method for their synthesis.

EFFECT: valuable properties of compounds.
