Abstract
In this research, ZnS nanoparticles were prepared and applied as heterogeneous reusable catalyst for synthesis of 1,5-benzodiazepines under grinding conditions at 70 °C. The multi-component reactions of aldehydes, dimedone and o-phenylenediamine were carried out under grinding conditions to obtain some 3,3-dimethyl-2,3,4,5,10,11-hexahydro-11-[aryl]-1H-dibenzo[b,e][1,4] diazepine-1-one derivatives. The present approach provides several advantages, including high yields, short reaction times, little catalyst loading and purification of compounds by crystallization method. The catalyst was characterized by using FT-IR, XRD, PL, EDX, SEM and TEM techniques.Graphical Abstract
