Aminodefluorination of polyhalogenbenzenes (chloropentafluoro-, 1,3-dichlorotetrafluoro-, sym-trichlorotrifluoro-, 1,2,3,5-tetrafluoro- and 1,2,4,5-tetrafluoro-3-trifluoromethylbezenes) in anhydrous ammonia was investigated. The optimal conditions for selective preparation of mono- and diamino derivatives, which are ensured by the reaction temperature, were elucidated. In some examples of diamine synthesis, in order to improve the selectivity of second aminodefluorination, it is advisable to separate the isomeric monoamino derivatives produced in the first step of the synthesis.
