FIELD: chemistry. n SUBSTANCE: invention relates to novel malononitryl derivatives of formula (I), which can be applied to fight pest insects. In formula (I) R 1 represents hydrogen atom; R 2 represents hydrogen atom; R represents hydrogen atom; R 4 represents C 1 -C 5 -alkyl group substituted with at least one halogen atom, C 2 -C 5 -alkenyl group; R 5 represents hydrogen atom, halogen atom, C 1 -C 5 -alkyl group; at least one of X 1 , X 2 and X 3 values represents CR 6 , the other represent nitrogen atoms; R represents hydrogen atom, halogen atom, cyanogroup, nitrogroup, formyl group, C 1 -C 5 -alkyl group optionally substituted with at least one halogen atom, C 1 -C 5 -alkyltiogroup, substituted with at least one halogen atom, C 2 -C 6 -alkylcarbonyl group substituted with at east one halogen atom, C 2 -C 5 -alkoxycarbonyl group or group (CH 2 ) m Q, where m = 0, and Q stands for phenyl; and in case when one of R 5 and R 6 is bonded with two atoms in adjacent positions or two R 6 are bonded with two atoms in adjacent positions, they can be bonded to each other in end positions with formation of C 2 -C 6 -alkandiyl group, or C 4 -C 6 -alkenediyl group. Invention also relates to composition and method used to fight pest-insects. n EFFECT: obtaining novel malononitryl derivatives of formula (I), which can be applied to fight pest-insects. n 11 cl, 90 ex |
