Bimetallic‐Catalyzed Oxidative Esterification Reaction Forming α‐Acyloxy Ether

Abstract A bimetallic‐catalyzed oxidative esterification reaction has been conducted between non‐activated C(sp 3 )–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 (Fe 2 Ni‐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.
