H3PMo12O40 immobilized chitosan/Fe3O4 as a novel efficient, green and recyclable nanocatalyst in the synthesis of pyrano-pyrazole derivatives

A novel nanomagnetic composite heteropolyacid immobilized chitosan/Fe 3 O 4 was prepared via a facile one-pot synthetic approach. This magnetically recoverable nanocatalyst, H 3 PMo 12 O 40 /chitosan/Fe 3 O 4 (PMo/chit/Fe 3 O 4 ), was fully characterized by XRD, FTIR, SEM and EDX analysis methods. A...

Zusammenfassung:A novel nanomagnetic composite heteropolyacid immobilized chitosan/Fe 3 O 4 was prepared via a facile one-pot synthetic approach. This magnetically recoverable nanocatalyst, H 3 PMo 12 O 40 /chitosan/Fe 3 O 4 (PMo/chit/Fe 3 O 4 ), was fully characterized by XRD, FTIR, SEM and EDX analysis methods. A rapid, efficient and the chemoselective synthesis of different pyrano-pyrazole derivatives was achieved in excellent yields via a one-pot four-component reaction in the presence of catalytic amount of PMo/Chit/Fe 3 O 4 .
