Abstract
In this research, a Schiff base-cobalt (II) catalyst containing crown ether, stabilized on cellulose nanoparticles (Crowned Imine-Co (II)@CNC) was prepared. This catalyst was identified by SEM, IR, TGA, XRD, EDX and TEM techniques. This compound was used as a heterogeneous catalyst in the synthesis of chromenes. Chromenes were synthesized with good efficiency (77% to 99%) and within a short time of 20 minutes through the reaction between diketones, malononitrile and various benzyl alcohol derivatives in water solvent. Reusing the recycled catalyst (up to 4 times) did not change the reaction efficiency. The difference between this method and other methods of synthesizing chromenes is by using benzyl alcohol derivatives instead of benzaldehyde.
