Abstract
AbstractWe synthesized an efficient bio‐based nano‐catalyst, – Fe3O4@nano linear dextrin/Sb+5 (Fe3O4@NLD/Sb+5) – from nano linear dextrin and antimony pentachloride via straightforward steps. The nano‐catalyst was used to synthesize solvent‐free 14‐aryl‐14H‐ dibenzo[a, j]xanthene derivatives based on 2‐aminobenzimide and different aldehydes. The synthesized nano‐catalyst bears many critical advantages: nontoxicity, biocompatibility, affordability, easy work‐up method, environmentally friendliness, and high yields, as well as being solvent‐free and operable under green conditions.
