Abstract :
1, 4-Diazabicyclo [2.2.2] octane (DABCO) was employed as a catalyst for one-pot synthesis of
pyrano[2,3-d] pyrimidinone derivatives and MWNT- pyrimidinones from condensation reactions
of aromatic aldehydes, malononitrile and thiobarbituric acid and MWNT-COCl . This method
delivers the advantages of a simple method, environment friendly procedure, mild reaction
conditions and high returns. The materials were characterized by Fourier transform infrared
spectroscopy, nuclear magnetic resonance, mass spectroscopy, elemental analysis, scanning
electron microscopy and Thermogravimetric analysis.
