The present invention provides a novel method for producing an ester group-containing compound and a derivative produced using the compound as a synthetic intermediate. The invention also provides a polymerizable composition containing the compound obtained by the production method and a film-shaped polymer obtained by polymerizing the polymerizable composition. The present invention is a method for producing an ester group-containing compound, the method including a mixing step of mixing a condensing agent, a Bronsted acid, a carboxylic acid, and a phenol or an alcohol to prepare a reaction mixture. The Bronsted acid selected is other than the condensing agent, the carboxylic acid, and the phenol.

The strategy of the synthesis of arylhydrazones via acceptorless dehydrogenative coupling of arylhydrazines with methanol was proposed and accomplished. In the presence of [Cp*Ir(2,2′-bpyO)(HO)] (0.5 mol %), a series of desirable products were obtained in high yields. It was found that functional groups in bpy are crucially important for the catalytic activity of iridium complexes. Furthermore, DFT
