Abstract
Acidic hydrolysis of Nphenyltetraflurophthalimide produced tetrafluorophthalic acid(Ⅰ).Dehydration of Ⅰ with toluene gave tetrafluorophthalic anhydride(Ⅱ).Reaction of Ⅱ with NH4OH gave 2carboxyl3,4,5,6tetrafluorobenzamide(Ⅲ).The title compound was obtained via Hofmann degradation and decarboxylation of Ⅲ.The total yield of this procedure reached 43%.The title compound was identified by MS and NMR.
