Solvent-Free one pot synthesis of benzo-[b]-1,4-diazepines using reusable sulfamic acid catalyst

α-β-Unsaturated carbonyl compounds on condensation with o-phenylenediamine in the presence of catalyst sulfamic acid under solvent free conditions, resulted in the formation of corresponding benzo-[b]-1,4-diazepines in excellent yields.
