X2 is a haloalkyl group or a halogen atom,
X3 is a hydrogen atom or a halogen atom;
Y is a nitro group, a cyano group, or a halogen atom;
R is a group of the formula
R' and R2, independently of each other and in each (CHR') and (CHR2) group, are a hydrogen atom, an unsubstituted or substituted (C,-C.) alkyl group, a (C1-C6) alkoxy group, or a (C1-C6) alkylthio group, provided that R' and R2 may not be alkoxy or alkylthio alpha to an -NH- moiety;

m is an integer from 2 to 10; and
n is an integer from 1 to 3; and wherein
when R1, R2, R4, or R5 is substituted alkyl group, there can be up to three substituents which can be the same or different and are selected from chlorine, bromine, fluorine, hydroxy, (C1-C6) alkoxy, (C1-C6) alkylthio, (C1-C6) alkylcarbonyl (C1-C6) alkoxycarbonyl, amino, mono- or di-(C,-Cs) alkylamino, (C1-C6) alkylcarbonyloxy and unsubstituted or substituted phenyl, phenoxy, or phenylthio each of these aromatic groups having up to three substituents which can be the same or different and are selected from chlorine, bromine, fluorine, hydroxy, (C1-C6) alkoxy, (C1-C6) alkylthio and (C1-C6) alkyl which is unsubstituted or substituted with up to three substituents which can be the same or different and are selected from chlorine, bromine, fluorine, hydroxy and (C,-C.) alkoxy.
