Description
Summary:A Green approach for benzothiazole / benzimidazole tethered imidazole derivative synthesis utilizing brick derived clay as a catalyst. Brick clay catalyst used in this synthesis has shown excellent catalytic activity by increasing efficiency, reducing the reaction time and most importantly it is reusable for further reaction runs. These derivatives were synthesized by four component condensation reaction that involvebenzil, aldehyde, 2-aminobenzimidazole / 2-amino-6-nitrobenzothiazole and ammonium acetate. The clay catalyst is characterized by FT-IR while the synthesized derivatives were characterized by FT-IR, 1H NMR and 13C NMR.Brick clay is a cheap, non-hazardous catalyst and can be reused up to many reaction runs with good to excellent yields.
