Description
Summary:In this project, poly(4-vinylpyridinum) trinitromethanide [P4VPH]C(NO 2 ) 3 was synthesized as a new heterogeneous catalyst in an easy and short way. The prepared catalyst was fully characterized using fourier transform infrared spectroscopy, energy dispersive spectrometer, field emission scanning electron microscopy, the brunauer–emmett–teller theory, thermo gravimetric analysis and X-ray diffraction. Then, the catalytic activity of this reagent was investigated in the promotion of the synthesis of 2,3-dihydroquinazolin-4(1 H )-one derivatives. Short reaction times, high yields of the products, carrying out the reaction under solvent-free conditions and easy separation of the catalyst from the reaction mixture are the main advantages of this method. Also, this heterogeneous catalyst can be reused up to five times without significant loss of its catalytic activity.
