Streamlining efficient and selective synthesis of benzoxanthenones and xanthenes with dual catalysts on a single...

Using two catalysts on a single support can improve reaction efficiency, higher yields, improved selectivity, and simplified reaction conditions, making it a valuable approach for industrial transformation. Herein, we describe the development of a novel and effective heterogeneous catalyst, WCl₆/CuCl_2, supported on graphitic carbon nitride (W/Cu@g-C₃N₄), which was synthesized under hydrothermal conditions. The structure and morphology properties of the W/Cu@g-C₃N₄ were characterized using various spectroscopic techniques, including FTIR, XRD, TEM, TGA, EDX, and SEM. The W/Cu@g-C₃N₄ support material enabled the rapid and efficient synthesis of benzoxanthenones and xanthenes derivatives in high yields under mild reaction conditions and short reaction times. The W/Cu@g-C₃N₄ catalyst was also found to be easily recyclable, and its catalytic performance did not significantly decrease after five times use. The findings suggest that W/Cu@g-C₃N₄ is a promising chemical synthesis catalyst with significant implications for sustainable and cost-effective organic synthesis.
