本文在乙酰基二茂铁的传统合成方法的基础上,用稀土固体超强酸SO2-4/TiO2/Y3+代替磷酸为催化剂,以二茂铁、乙酸酐为原料探索合成乙酰基二茂铁,找到了一种合成乙酰基二茂铁的新方法,并对反应条件进行了简单的讨论,实验结果表明:SO2-4/TiO2/Y3+类固体超强酸可以催化合成乙酰基二茂铁.
Based on the traditional synthesis method of acetylferrocene, the synthesis of acetylferrocene with ferrocene and acetic anhydride as starting materials was studied by using rare earth solid superacid SO2-4 / TiO2 / Y3 + instead of phosphoric acid as catalyst. A new method for the synthesis of acetylferrocene has been discussed. The reaction conditions have been briefly discussed. The experimental results show that SO2-4 / TiO2 / Y3 + solid superacid can catalyze the synthesis of acetylferrocene.
