Ss. Laev et Vd. Shteingarts, REDUCTIVE DEFLUORINATION OF PERFLUOROARENES BY ZINC IN AQUEOUS AMMONIA, Journal of fluorine chemistry, 91(1), 1998, pp. 21-23
A very simple reductive system such as zinc in aqueous ammonia has bee
n shown to be applicable for hydrodefluorination of some perfluoroaren
es (hexafluorobenzene, octafluorotoluene, octafluoronaphthalene and de
cafluorobiphenyl) under mild conditions. In all cases an ammonia conce
ntration effect has been observed. Moreover, for octafluoronaphthalene
, the presence of NH4Cl is of importance and for decafluorobiphenyl th
is factor and the addition of an organic solvent to the aqueous ammoni
a are significant. (C) 1998 Elsevier Science S.A. All rights reserved.
