Abstract

Abstract 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 ...
