Synthesis, Characterization, and Catalytic Application of SnP2O7 for the Highly Efficient Synthesis of Xanthene Derivatives

AbstractThis study introduces a mono-ammonium phosphate-based heterogeneous catalyst that possesses characteristics of simplicity, reusability, and recoverability, making it well-suited for multicomponent reactions. The prepared catalyst underwent comprehensive characterization using Fourier-transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD) patterns, scanning electron microscopy (SEM), and energy-dispersive X-ray spectroscopy (EDX). Employing this catalyst in a one-pot multicomponent approach, it becomes possible to synthesize xanthene derivatives efficiently. The results showcase the impressive performance of the novel SnP2O7, which acts as a heterogeneous catalyst in traditional reactions, leading to the desired products with yields ranging from good to excellent and within a short reaction time. Notably, SnP2O7 exhibits remarkable stability in its catalytic activity, enabling its use for up to five cycles without experiencing a significant decrease in yield.Keywords: Heterogeneous catalystgreen chemistrythree-component reactionxanthene derivatives Disclosure statementNo potential conflict of interest was reported by the author(s).
