Abstract
Aromatic carboxylic acids react with arylamines in polyphosphoric acid solution at 180-200° to furnish aminobenzophenones in appreciable yield. Diphenylamine, triphenylamine, and 2-aminobiphenyl yield heterocyclic bases. Substituted benzanilides are converted to aminobenzophenones by the hot reagent. Mechanisms to account for the results are proposed.
