Abstract :

The reaction of nano-cellulose and antimony pentachloridein dichloromethane gave nano-cellulose-SbCl5. Also nano-cellulose-SbCl5 has beencharacterized by energy dispersive X-ray spectroscopy(EDX), scanning electron microscopy (SEM)and Fourier transform infrared spectroscopy(FTIR).Nano-cellulose-SbCl5has been applied as a nano-catalyst for synthesis of pyrano[2,3-d]pyrimidines from the simple one-pot reaction between aryl aldehydes,barbituric acid orthiobarbituric acid and malononitril.Cleanliness, simple methodology, short time, and excellentyields of products are some advantages of this method.
