An effective approach to reusing a homogeneous catalyst has been demonstrated. A ferrocene-based bulky pyridine has been synthesized and utilized as a homogeneous catalyst for the synthesis of benzoylfumarates as well as for acetylation. After the reaction, the catalyst was separated by simple precipitation and reused without appreciable loss of activity.
已经证明了一种有效的方法来重复使用均相催化剂。合成了基于
二茂铁的大体积
吡啶,并将其用作均相催化剂,用于合成苯甲酰
富马酸酯以及乙酰化反应。反应后,催化剂通过简单的沉淀分离出来,并且可以重复使用而不会显著损失活性。
