چکیده

An efficient and simple procedure for the preparation of silver functionalized on hydroxyapatite-core-shell magnetic γ-Fe2O3 nanoparticles (γ-Fe2O3@HAp-Ag)as an enviromentaly efficient magnetically recoverable and reusable catalyst is described, and it is used for the one-pot synthesis of 14-aryl-14H-dibenzo[a,j]xanthenes via a cost-effective and atom-economical procedure from substituted benzaldehydes and β-naphthol under solvent-free conditions at 60 °C. The attractiveness of this protocol lies in its green approach in that the catalyst is easily recoverable using an external magnet, which makes the process economical.
