摘要: The present invention provides a method for preparing dimer of a monohydroxy aromatic compound. In the method of the present invention, oxidative coupling reaction of a monohydroxy aromatic compound represented by formula [I]: Ar—OH [I] wherein Ar represents an optionally substituted aromatic group is carried out in a nitrogen containing polar solvent in the presence of a copper salt. By the method of the instant invention, dimer of the monohydroxy aromatic compound can be obtained in high yield.
