Abstract: H exafluorophosphoric acid/polyaniline was synthesized using H exafluorophosphoric acid and polyaniline, and its catalytic activity was studied for the synthesis of 1, 5-Benzodiazepine Derivatives by cyclization of o-phenylenediamine and ketones. The effects of the catalyst amount, temperature and solvent on reaction have been researched. It has been proved that the catalyst was of good activity and reusability.

Key words: h exafluorophosphoric acid; polyaniline; 1, 5-Benzodiazepine
