FLUOROALKENYL COMPOUNDS OR THEIR AGRICULTURALLY ACCEPTABLE SALTS FOR STRUGGLE AGAINST PLANT INFECTION WITH NEMATODES, METHOD OF STRUGGLE AGAINST PLANT INFECTION WITH NEMATODES AND METHODS OF SYSTEMIC SUPPRESSION OF PLANT INFECTION WITH NEMATODES Russian patent published in 1998 - IPC

FIELD: organic chemistry and technology. SUBSTANCE: invention relates to fluoroalkenyl compounds of the general formula (I): (X)(Y)C=C(Z)--Q where X and Y - fluorine; Z - hydrogen, fluorine; n = 1, 3, 5, 7, 9, 11; Q - at condition that if X and/or Y - fluorine and Q - (C=O)-R¹¹ then each X, Y, Z - fluorine and n = 1; W - anion of mineral or organic acid; R² - possibly substituted phenyl; R³, R⁴, R⁵- - hydrogen and others; R⁶ - hydrogen, -alkyl and others; R¹¹- - halogen, NHOH and others, and to their agriculturally acceptable salts. Invention relates to also the composition used for struggle against plant infection with nematodes containing compound of the formula (I) and a method of struggle against plant infection with nematodes which involves treatment of plant locus with compound of the formula (I), and to a method of systemic SUPPRESSION of plant infection with nematodes by plants treatment with compound of the formula (I). EFFECT: improved method of synthesis, enhanced effectiveness of compounds synthesized. 27 cl, 5 tbl
