摘要：
Monoammonium salt of 12-tungstophosphoric acid [(NH4) H2PW12O40] was found to be a practical, inexpensive, reusable, and efficient heterogeneous catalyst for the preparation of 1,5-benzodiazepine derivatives of o-phenylenediamine and ketones. The heteropolyacid-based catalyst has the advantages of simple workup procedure, water insolubility with good activity, and high-yielding reaction for the synthesis of 1,5-benzodiazepine derivatives.
