NOVEL DERIVATIVES OF CARBOXYLIC ACID ESTERS, METHOD OF THEIR SYNTHESIS, INSECTICIDES CONTAINING THEREOF Russian patent published in 2001 - IPC

FIELD: organic chemistry, insecticides. SUBSTANCE: invention relates to novel derivatives of carboxylic acid esters of the general formula (I) where R₁ means alkyl group with linear or branched chain having 1-4 carbon atoms; R₂ means group of the formula (IV) where R₄ means hydrogen atom or ethynyl group; R₅ and R₆ are similar or distinct and taken among the group including hydrogen atom or methyl group; R₇ means hydrogen atom; R₈ is taken among propargyl, methoxymethyl or methyl-thio-group. Method of synthesis of derivatives of carboxylic acid esters of the general formula (I) involves interaction of carboxylic acids or reactive derivatives of the general formula (XII) with alcohols or their reactive derivatives of the general formula (XIII) HO-R₂ (XIII). Insecticides providing protection from insects have derivatives of carboxylic acid esters of the general formula (I) as an active agent. EFFECT: new compounds indicated above, improved method of synthesis. 11 cl, 3 tbl
