V2O5 based quadruple nano-perovskite as a new catalyst for the synthesis of bis and tetrakis heterocyclic compounds

In this article, we presented a novel, efficient and facile approach for using strontium titanate supported catalyst in organic synthesis. Bis and tetrakis of coumarin, indole and xanthene derivatives can effortlessly have prepared using V2O5/perovskite nanoparticles (NPs) under solvent-free condition. V2O5/perovskite in (NPs) was prepared and identified using Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD) and scanning electron microscope supported with energy dispersive X-ray (SEM/EDAX). Calculated crystal size was from the intense XRD peaks was found to range between 50-60 nm in agreement with that obtained from the transmission electron microscopic investigation. EDAX analysis and mapping images reveal a homogenous distribution of all constituents with their calculated ratios in the synthesized catalyst.
