A bimetallic-catalyzed oxidative esterification reaction has been conducted between non-activated C(sp³)–H bonds of symmetric ethers and carboxylic acids with the presence of di-tert-butyl peroxide as the oxidant through a cross-dehydrogenative coupling (CDC) reaction. This approach allows the derivatives of cyclic ether substrates to interact with aromatic acids, giving excellent yields for the formation of α-acyloxy ethers. The bimetallic organic frameworks catalyst (Fe₂Ni-BDC) that had been synthesized by solvothermal method was successfully utilized for the formation of α-acyloxy ethers based on the CDC reaction of carboxylic acid with diethylene oxide (approx. 84 % product yield). Besides, this material was also used as catalyst for research scope of benzoic acid containing various substituents.

双金属催化氧化酯化反应生成α-酰氧基醚

在二叔丁基过氧化物作为氧化剂的情况下，通过交叉脱氢偶联 (CDC)在对称醚和羧酸的非活化 C(sp ³ )-H 键之间进行了双金属催化的氧化酯化反应。反应。这种方法允许环状醚底物的衍生物与芳香酸相互作用，从而为α-酰氧基醚的形成提供极好的产率。成功利用溶剂热法合成的双金属有机骨架催化剂（Fe _{2 Ni-BDC）生成}α-酰氧基醚，基于羧酸与环氧乙烷的 CDC 反应（约 84 % 的产品收率）。此外，该材料还用作催化剂，用于含各种取代基苯甲酸的研究范围。
