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 or thiobarbituric acid and malononitril.Cleanliness, simple methodology, short time, and excellent yields of products are some advantages of this method.
