Selective mono-and diamination of polyfluorinated benzenes and pyridines with liquid ammonia

Amination of pentafluoropyridine, 2,3,5,6-tetrafluoropyridine, 4-chlorotetrafluoropyridine, 3,5-dichlorotrifluoropyridine, octafluorotoluene, α,α,α,2,3,5,6-heptafluorotoluene, decafluoro-m-xylene, decafluorobiphenyl, hexafluorobenzene, and pentafluorobenzene with liquid ammonia was investigated. Bis-aminodefluorination temperatures for the majority of substrates were shown to exceed significantly the corresponding temperatures of monoaminodefluorination. The optimal conditions for selective preparation of mono-and diaminopolyfluoro(het)arenes were elucidated. An efficient method for isolation of particular polyfluorophenylenediamines from product mixtures formed in nonselective reactions of pentafluorobenzene and hexafluorobenzene with aqueous ammonia based on complexation with a crown ether is proposed.

Synthesis of photoactive polyfunctional molecules based on 1-aryloxyanthraquinone aminoderivatives

By alternating stages of condensation of 1-(4-tert-butylphenoxy)-2-amino-9,10-anthraquinone with 5-nitroisophthaloyl dichloride, cyanuric chloride, and 4-aminobenzocrown ethers with stages of catalytic reduction of nitro group photoactive polyfunctional compounds were prepared containing both several photoactive groups and complex-forming crown ether moieties.
