A novel efficient synthetic method for 2,2′,3,3′-biphenyltetracarboxylic dianhydride
چکیده انگلیسی

A novel approach to the synthesis of 2,2′,3,3′-biphenyltetracarboxylic dianhydride is described. The target compound was prepared by a nickel-catalyzed coupling reaction of dimethy 3-chlorophthalate (3-DMCP) for 4 h at 70–80 °C, followed by subsequent hydrolysis of tetra-ester in acid solution and dehydration of tetra-acid, with overall yield of 68%. The structures of the products were characterized by IR, 1H NMR and 13C NMR respectively.
