摘要： A preparation method of a sulfur-containing biphenylsulfur-containing biphenyl compound shown by the general formula (I) has a reaction formula as follows:

Each substituent in the formula is defined in the description. In the method, halogeno benzene shown by the general formula (II) generates a coupling reaction in a catalytic system composed of a nickel compound and at least one ligand under the combined action of metallic zinc to obtain the sulfur-containing biphenyl compound shown by the general formula (I).
