Nano-Fe۳O۴/TiCl۲/cellulose as an Efficient and Ggreen Magnetic Nanocatalyst for the Synthesis of ۲,۳-Dihydro-۲-substituted-۱H-naphtho[۱,۲-e][۱,۳]oxazine Derivatives

Nano-Fe۳O۴/TiCl۲/cellulose as a green and recyclable nanocatalyst was synthesized and characterized by FT-IR, FESEM, TEM, XRF, BET, VSM, EDX and XRD. The prepared magnetic nanocatalyst was applied for the synthesis of ۲,۳-dihydro-۲-substituted-۱H-naphtho[۱,۲-e][۱,۳]oxazine under room temperature grinding condition. Short reaction time, high yield, green media, easy work-up, simple magnetic recovery and reusability of the catalyst are the important features of the present protocol.
