Selective mono- and diamination of some polyhalogenbenzenes in anhydrous ammonia

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 sel

Amino- and hydrodefluorination of polyfluoroaromatic amines with aqueous ammonia in a steel autoclave. Synthesis of highly pure tetrafluorophenylenediamines

The action of aqueous ammonia on liexafhiorobenzene in a steel autoclave at 180-220 °C yields a mixture of isomeric tet rafluorophenylenediamines and 2,4,5-trifhioroplienylene-1,3-diamine. The content of the hydrodefluorination product significantly depends on the reaction temperature and time. Tetrafluorophenylene-1,3-diamine undergoes hydrodefluorination with aqueous ammonia in a steel autoclave at 200 °C to give 2,4,5-trifluorophenylene-1,3- diamine; when the additives of NH4F and/or FeCl3 are present, 2,5-difluorophenylene-1,3-diamine is additionally formed. The hydrodefluorination products are not formed during bis-aminodefluorination of hexafluorobenzene with aqueous ammonia in a glass reactor or with anhydrous ammonia (in a mixture with aprotic solvent) in a steel autoclave.

Fluorobenzene derivatives

The invention relates to a process for the preparation of aminohalobenzenes which are useful as intermediates in the manufacture of agrochemicals, pharmaceuticals, and dyestuffs. The process involves the simultaneous hydrolysis in an acid medium of the two cyano groups in a 1,3-dicyanoaminohalobenzene to yield an aminohalobenzene.
