Abstract
Aqueous ammonia has been found to be a good and versatile medium for t he reductive defluorination of polyfluoroarenes by zinc. Upon the redu ction of pentafluorobenzoic acid, 2,3,4,5,6-pentafluorobenyl alcohol, pentafluoropyridine and heptafluoro-2-naphthoic acid individual produc ts derived from the removal of one fluorine atom have been obtained.
