Fabrication of ۳,۴-dihydropyrimidin-۲-(۱H)-ones/thione compounds via Cu۲V۲O۷ nanocatalyst synthesized by solid state method

Synthesis of Cu۲V۲O۷ nanoparticles was performed successfully using Cu(NO۳)۲ and V۲O۵ raw compounds in one step solid state method. Cu۲V۲O۷ nano powders were used as photocatalysts to remove pollutant dye under visible light irradiation. X-ray diffraction (XRD) technique was applied to characterize the crystal phase type of the as-prepared sample. The XRD results showed that the patterns had a main Cu۲V۲O۷ structure with a space group of C۲/c. Field emission scanning electron microscopy (FESEM) images showed that the synthesized Cu۲V۲O۷ particles had mono-shaped sphere morphologies. The as-prepared Cu۲V۲O۷ nanomaterial exhibited high catalytic activity in multi-component reaction for the one-pot synthesis of heterocyclic compound ۳,۴-dihydropyrimidin-۲(۱H)-ones (DHPMs). Additionally, the nanocatalyst can be reused for several times without apparent loss of its catalytic activity, confirming it is a highly stable and reusable material for this reaction. It is found that the optimum values for catalyst amount, reaction time and temperature are ۵۰ mg, ۵۰ min and ۹۰ ºC, respectively.
