Abstract

The cyclocondensation of 1,2-phenylenediamine (I) with acetone was investigated in the presence of Fe-containing microporous nickel phosphate molecular sieves (Fe-VSB-5) and Fe-containing mesoporous mesophase materials (Fe-MMM). The main product was 2,3-dihydro-2,2,4-trimethyl-1H-1,5-benzodiazepine (1,5-benzodiazepine) with 86–88% yield at 50 °C, with an acetone/(I) molar ratio of 2.5 in methanol as the reaction medium. The Fe content was found to affect not only the reaction rate but also yield of 1,5-benzodiazepine. The high reaction rate and yield of 1,5-benzodiazepine were—achieved with isolated iron sites in frameworks of Fe-VSB-5 and Fe-MMM.
