Abstract :
Nano-Fe3O4/TiCl2/cellulose as a new, green, bio-based and recyclable catalyst was synthesized by bonding TiCl4 to hydroxyl groups of nano-cellulose and Fe3O4 nanoparticles. This catalyst was characterized by FT-IR, FESEM, TEM, XRF, BET, VSM, EDX and XRD. As a first report, the catalytic activity of nano-Fe3O4/TiCl2/cellulose was investigated in the synthesis of 2,3-dihydroquinazolin-4(1H)-ones in good to excellent yields under mild conditions.
