ACRYLONITRILE COMPOUND OR ITS SALT, METHOD OF ITS SYNTHESIS, MITICIDE, INSECTICIDE AND AGENT CONTAINING ABOVE- MENTIONED COMPOUND FOR CONTROL OF OVERGROWING WITH MARINE ORGANISMS, METHODS OF CONTROL OF INSECTS, MITES AND MARINE ORGANISMS

FIELD: organic chemistry, chemical technology. SUBSTANCE: invention describes novel compound of acrylonitrile of the formula (I) or its salt where Q represents compounds of formulas (Qa) , (Qb) or (Qc) ; Y represents =C(R4)- or = N-; R1 represents alkyl, alkoxyalkyl and so on; R2 re[resents halogen atom, alkyl or halogenalkyl; R3 represents halogen, alkyl, halogenalkyl and so on; R4 represents hydrogen atom; R5 represents alkyl, halogenalkyl and so on; l = 1 or 2; m = 1 or 2; n = 0; q = 1; w = 0, 1 or 2. New compounds are used as active components of miticide, insecticide and agent for control of overgrowing with marine organisms. Invention describes also method of synthesis of tehse compounds, intermediate compounds for their synthesis, miticide, insecticide, agent for control of overgrowing with marine organisms containing acrylonitrile compounds, methods of control of mites, insects and method of control of overgrowing with marine organisms. EFFECT: improved method of synthesis, valuable properties of compounds. 14 cl, 5 tbl
