Aniline → N-Phenyltetrachlorophthalimide

Participants

Reaction Steps

In a preferred embodiment tetrachlorophthalic anhydride is refluxed with aniline in the presence of glacial acetic acid for 5 to 10 hours to form tetrachloro-N-phenylphthalimide which is reacted with KF in sulfolane in the presence of tributylhexadecylophosphonium bromide under nitrogen at 140° C. to 160° C. for 10 to 15 hours to form tetrafluoro-N-phenylphthalimide which in turn is hydrolyzed by refluxing with 50% H2SO4 for 15 to 25 hours. The tetrafluoro-N-phenylphthalimide is a novel compound.
