<p>New fluorinated hexane compounds and their use in industrial synthesis. These compounds are characterised in that they correspond to the following general formula (II): <IMAGE> in which X'2, X'3 and X'4 (which correspond, one by one, to X2, X3 and X4 or X1, X2 and X3 of formula I), which are similar or different, represent a halogen or a pseudohalogen, preferably a halogen, advantageously chlorine and fluorine, with the condition that when R1 is hydroxyl, cyano, amido, imido, ethoxy, benzyloxy, cyclohexyl and tert-butyl, the halogens cannot all be simultaneously chlorine and R4, R3 and R5 simultaneously equal to H; in which R1 represents a hydrogen, a hydrocarbon chain such as, for example, an alkyl chain, an aromatic chain or an alkoxy, carbonyl, carboxyl or acyloxy, or even hydroxyl, group; in which R4 represents a hydrogen, a fluorine atom, a hydrocarbon chain such as, for example, an alkyl chain, an aromatic chain or a carbonyl, carboxyl or carboxamide group or even a radical bonded to the hexane ring via a chalcogen or via an element from column V, preferably from the first period, such as an amido, alkoxy or acyloxy group; in which the radicals R3 and R5, which are different or preferably similar, represent a fluorine atom, or preferably hydrogen, or also hydrocarbon chains such as defined above for R4.</p> |
