  A novel, efficient and recyclable catalyst was prepared by covalent grafting of polyfluorinatedzinc(II)phthalocyanine complex onto functionalized silica gel. The activity of the catalyst was investigated for the solvent-free synthesis of 1,5-benzodiazepines at room temperature. The immobilized catalyst was characterized by elemental analysis (CHN), diffuse reflectance UV-Vis spectroscopy, solid-state C-13 CPMAS and Si-29 CPMAS NMR spectroscopy, X-ray diffraction (XRD), scanning electron microscopy (SEM), BET surface area analysis, energy dispersive X-ray fluorescence (ED-XRF), Fourier transform Infrared (FT-IR) and atomic absorption spectroscopy (AAS) techniques. Short reaction time, mild reaction conditions, high turnover numbers, and easy recovery and reusability of the catalyst make this method a novel, economic and waste-free chemical process for the synthesis of biologically important 1,5-benzodiazepines.

  Silica gel-supported sulfuric acid has been found to be an efficient catalyst for the synthesis of 1,5-benzodiazepines from o-phenylenediamine and ketones in acetonitrile solvent. This method is simple, effective, and environmentally friendly and gives better yields. Compared to the classical reaction conditions, this new method consistently has the advantage of excellent yields (80–97%) and short
