Abstract An eco-compatible and solvent-free protocol for the synthesis of xanthenediones has been developed with high substrate scope using inexpensive and nontoxic VOSO4 as reusable catalyst. Xanthenediones were characterized by different spectral analysis such as FT-IR, 1HNMR, 13CNMR, mass spectrometry and elemental analysis. The synthetic attributes of xanthenediones were also demonstrated through different data of Computational studies. Furthermore, Green chemistry metrics data like low E-factor and PMI make the present method more sustainable as compared to earlier literature reports.

VOSO4催化绿色合成呫吨二酮的实验研究和计算研究

摘要 使用廉价且无毒的 VOSO4 作为可重复使用的催化剂，开发了一种生态相容且无溶剂的合成呫吨二酮的方案，具有高底物范围。呫吨二酮通过不同的光谱分析如FT-IR、1HNMR、13CNMR、质谱和元素分析来表征。呫吨二酮的合成属性也通过计算研究的不同数据得到证实。此外，与早期文献报告相比，绿色化学指标数据（如低 E 因子和 PMI）使本方法更具可持续性。
