Summary:PROBLEM TO BE SOLVED: To provide a novel process for carbonylation of ethers.SOLUTION: The process comprises the following steps of: a) introducing an ether having 3 to 30 carbon atoms; b) adding a phosphine ligand and a compound having Pd, or adding a complex having Pd and a phosphine ligand; c) adding an alcohol; d) supplying CO; and e) heating the reaction mixture to react the ether to form an ester; where the phosphine ligand is a compound represented by formula (I).SELECTED DRAWING: None 【課題】エーテルのカルボニル化のための新規のプロセスの提供。【解決手段】以下のステップを含むプロセス。ａ）３〜３０個のＣを有するエーテルを導入するステップと、ｂ）ホスフィン配位子とＰｄを含む化合物とを加えるか又はＰｄとホスフィン配位子とを含む錯体を加えるステップと、ｃ）アルコール加えるステップと、ｄ）ＣＯを供給するステップと、ｅ）前記反応混合物を加熱して、エステルを形成するためにエーテルを反応させるステップと、を含むプロセスであって、前記ホスフィン配位子は、式（Ｉ）で表される化合物。【選択図】なし
