PROBLEM TO BE SOLVED: To provide a high-yield production method for alkoxycarbonylation of long-chain ethylenically unsaturated compounds and alkoxycarbonylation of mixtures of ethylenically unsaturated compounds.SOLUTION: In the method, an ethylenically unsaturated compound is converted to an ester using a 1,1'-bis(phosphino)ferrocene compound represented by formula (I) and a catalyst including Pd.
