摘要

The new (伪-Fe₂O₃)-MCM-41-SO₃H catalyst was prepared directly through the reaction of chlorosulfonic acid with silica-coated nanoparticles (伪-Fe₂O₃)-MCM-41 and used as a magnetically recyclable catalyst for an efficient one-pot synthesis of N-aryl-2-amino-1,6-naphthyridine derivatives. The catalyst with 10 wt%of loaded iron oxide nanoparticles could be recovered from the reaction mixture by an external magnet and reused without significant decrease in activity even after 5 runs. This new prepared catalyst exhibited better activities to other commercially available sulfonic acid catalysts.
