Nano-Fe3O4/TiCl2/cellulose as an Efficient and Ggreen Magnetic Nanocatalyst for the Synthesis of 2,3-Dihydro-2-substituted-1H-naphtho[1,2-e][1,3]oxazine Derivatives

Abstract

Nano-Fe3O4/TiCl2/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 2,3-dihydro-2-substituted-1H-naphtho[1,2-e][1,3]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.
