    • The present invention relates to new fluorinated hexane compounds corresponding to the following general formula (II): ##STR1## in which X'.sub.2, X'.sub.3, and X'.sub.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 R.sub.1 is hydroxyl, cyano, amido, imido, ethoxy, benzyloxy, cyclohexyloxy and tert-butoxy, not all the halogens can simultaneously be chlorine and R.sub.4, R.sub.3 and R.sub.5 are simultaneously equal to H; R.sub.1 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; R.sub.4 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 R.sub.3 and R.sub.5, 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 R.sub.4.
    • 本发明涉及对应于以下通式(II)的新的氟化己烷化合物:其中X'2,X'3和X'4相同或不同,表示卤素或假卤素, 优选卤素,更优选氯和氟,条件是当R1是羟基,氰基,酰氨基,亚氨基,乙氧基,苄氧基,环己氧基和叔丁氧基时,不是所有的卤素都可以同时为氯,R4,R3和R5 同时等于H; R 1表示氢,烃链如烷基链,烷氧基,环烷基醚,芳族基团,芳族醚或烷氧基,羰基,羧基或酰氧基,氰基,酰胺基,亚氨基或羟基; R4表示氢,氟原子,烃链,例如烷基链,芳族基团或羰基,羧基或羧酰胺基团,或者由硫属化合物连接到己烷环上的基团,或者由 优选第一阶段的V族如酰氨基,烷氧基或酰氧基; 其中不同或优选相同的基团R3和R5表示在R4的情况下如上所定义的氟或优选氢原子或烃链。
