  Molybdate sulfonic acid (MSA) as a highly efficient catalyst was synthesized and employed for the synthesis of octahydroxanthene-1,8-dione derivatives. MSA efficiently catalyzed condensation of a wide range of aryl aldehydes and cyclohexane-1,3-diones to obtain octahydroxanthene-1,8-diones. It was characterized by X-ray fluorescence (XRF), X-ray diffraction (XRD), and FT-IR spectroscopy. This catalyst

  合成了作为高效催化剂的钼酸磺酸（MSA），并用于合成八氢氧杂蒽-1,8-二酮衍生物。MSA有效地催化了各种芳基醛与环己烷-1,3-二酮的缩合反应，从而得到八氢氧杂蒽-1,8-二酮。它的特征在于X射线荧光（XRF），X射线衍射（XRD）和FT-IR光谱。该催化剂可以回收并在其他反应中重复使用几次，以保持其高活性。这种新颖且绿色的方法非常便宜，并具有许多优点，例如产率高，使用可回收且环保的催化剂以及后处理程序简单。
