FIELD: chemistry. ^ SUBSTANCE: invention relates to novel malononitryl derivatives of formula (I), which can be applied to fight pest insects. In formula (I) R1 represents hydrogen atom; R2 represents hydrogen atom; R represents hydrogen atom; R4 represents C1-C5-alkyl group substituted with at least one halogen atom, C2-C5-alkenyl group; R5 represents hydrogen atom, halogen atom, C1-C5-alkyl group; at least one of X1, X2 and X3 values represents CR6, the other represent nitrogen atoms; R represents hydrogen atom, halogen atom, cyanogroup, nitrogroup, formyl group, C1-C5-alkyl group optionally substituted with at least one halogen atom, C1-C5-alkyltiogroup, substituted with at least one halogen atom, C2-C6-alkylcarbonyl group substituted with at east one halogen atom, C2-C5-alkoxycarbonyl group or group (CH2)mQ, where m = 0, and Q stands for phenyl; and in case when one of R5 and R6 is bonded with two atoms in adjacent positions or two R6 are bonded with two atoms in adjacent positions, they can be bonded to each other in end positions with formation of C2-C6-alkandiyl group, or C4-C6-alkenediyl group. Invention also relates to composition and method used to fight pest-insects. ^ EFFECT: obtaining novel malononitryl derivatives of formula (I), which can be applied to fight pest-insects. ^ 11 cl, 90 ex |
