Abstract
|
In this research, novel and suitable method was used for synthesis of N-hetrocycles such as 3,4- dihydropyrimidin-2(1H)-ones and 4,4-(arylmethylene)-bis(3-methyl-1H-phenyl-pyrazol-5-ol)s derivativy using nano catalyst niacin-sulfonic acid chloride-functionalized Fe3O4 nanoparticles and also a new catalyst a mixture of sulfuric acid and inorganic salt were used. The advantages of these methods are using solvent free, none toxic , eco friendly ,high yield and suitable of time reaction. Nano catalyst niacin-sulfonic acid chloridefunctionalized Fe3O4 nanoparticles was identified by IR, XRD ،EDX،SEM ،TGA and VSM.The hetrocyclic compounds were identified by IR and NMR.
