The target compound was prepared by a nickel-catalyzed couplirtg reaction of dimethy 3-chlorophthalate （3-DMCP） for 4 h at 70-80 ℃, 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.展开更多
