FIELD: organic chemistry and technology. SUBSTANCE: invention relates to fluoroalkenyl compounds of the general formula (I): (X)(Y)C=C(Z)-<EMI ID=0.303 HE=6 WI=15 TI=CHI>-Q where X and Y - fluorine; Z - hydrogen, fluorine; n = 1, 3, 5, 7, 9, 11; Q - <EMI ID=0.304 HE=15 WI=75 TI=CHI> at condition that if X and/or Y - fluorine and Q - (C=O)-R then each X, Y, Z - fluorine and n = 1; W - anion of mineral or organic acid; R - possibly substituted phenyl; R<SP>3</SP>, R<SP>4</SP>, R<SP>5</SP>- - hydrogen and others; R - hydrogen, <EMI ID=0.305 HE=6 WI=15 TI=CHI>-alkyl and others; R<SP>11</SP>- - 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 tblr
