At room temperature, a bifunctional phosphine-gold(I) catalyst was used to catalyze the nucleophilic addition/cyclization reaction of o-phenylenediamines with alkynes to generate 1,5-benzodiazepines in one step. The reaction has the advantages of high atomic-economy, simple raw materials, convenient operation and mild reaction conditions.

Key words: phthaline diamine, alkyne, bifunctional phosphine ligand, gold catalysis, 1,5-benzodiazepine
