Ss. Laev et al., ON THE DIFFERENCE IN THE RESULTS OF REDUCTIVE DEFLUORINATION OF PENTAFLUOROBENZOIC ACID BY SODIUM AND ZINC IN LIQUID-AMMONIA MEDIUM, Tetrahedron letters, 36(26), 1995, pp. 4655-4658
Under the reduction of pentafluorobenzoic acid in liquid ammonia by so
dium the deep defluorination with removal of three or more fluorine at
oms has been observed, whereas with zinc only the product of para-defl
uorination has been obtained.
