Pandey, Himanshu; Shrivastava, S. P. published their research in Oriental Journal of Chemistry in 2021. The article was titled 《One pot synthesis, characterization of benzothiazole/benzimidazole tethered imidazole derivatives using clay as catalyst》.Formula: C7H7N3 The article contains the following contents:
A green approach for benzothiazole/benzimidazole tethered imidazole derivative synthesis utilizing brick derived clay as a catalyst were reported. Brick clay catalyst used in this synthesis were shown excellent catalytic activity by increasing efficiency, reducing the reaction time and most importantly it was reusable for further reaction runs. These derivatives were synthesized by multi component condensation reaction that involved benzil, aldehyde, 2-aminobenzimidazole/2-amino-6-nitrobenzothiazole and ammonium acetate. The clay catalyst was characterized by FT-IR while the synthesized derivatives were characterized by FT-IR, 1H NMR and 13C NMR. Brick clay was a cheap, non-hazardous catalyst and were reused up to many reaction runs with good to excellent yields. In the experimental materials used by the author, we found 1H-Benzo[d]imidazol-2-amine(cas: 934-32-7Formula: C7H7N3)
1H-Benzo[d]imidazol-2-amine(cas: 934-32-7) can be used in the hydrolysis of a choline carbonate. It was also used in the synthesis of imidazo[1,2-a]benzimidazoles.Formula: C7H7N3
