  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.

  揭示了一种通过在存在至少一种钯盐、一种铜盐和一种β-二羰基化合物的催化剂的情况下，通过氧化偶联邻苯二甲酸酯来制备二苯四羧酸酯的方法，其中β-二羰基化合物间歇地以小于30分钟的间隔或连续地供给到反应混合液中。该方法特别允许选择性和经济地生产不对称的二苯四羧酸四酯，如2,3,3′,4′-二苯四羧酸四酯。
