The present invention relates to new fluorinated hexane compounds corresponding to the following general formula (II): STR1 in which X'2, X'3 and X'4 are the same or different, and denote a halogen or a pseudohalogen, preferably a halogen, more preferably chlorine and fluorine, with the condition that, when R1 is hydroxyl, cyano, amido, imido, ethoxy, benzyloxy, cyclohexyloxy and tert-butoxy, not all the halogens can simultaneously be chlorine and R4, R3 and R5 are simultaneously equal to H; R1 denotes a hydrogen, a hydrocarbon chain such as an alkyl chain, alkoxy, cycloalkyl ether, an aromatic group, aromatic ether or an alkoxy, carbonyl, carboxyl or acyloxy, cyano, amido, imido or hydroxyl group; R4 denotes a hydrogen, a fluorine atom, a hydrocarbon chain such as, for example, an alkyl chain, an aromatic group or a carbonyl, carboxyl or carboxamide group or else a radical joined to the hexane ring by a chalcogen or by an element of Group V, preferably of the first Period, such as an amido, alkoxy or acyloxy group; in which the radicals R3 and R5, which are different or preferably the same, denote a fluorine, or preferably hydrogen, atom or also a hydrocarbon chain as defined above in the case of R4.
