  Disclosed is a method for producing a biphenyltetracarboxylic acid ester by oxidative coupling a phthalic acid ester by using a catalyst comprising at least a palladium salt, a copper salt and a β-dicarbonyl compound in the presence of a molecular oxygen, wherein the β-dicarbonyl compound is supplied into a reaction mixture liquid intermittently at an interval of less than 30 minutes, or continuously. This method allows, in particular, the selective and economical production of an asymmetric biphenyltetracarboxylic acid tetraester such as 2,3,3′,4′-biphenyltetracarboxylic acid tetraester.
