| abstract |
The invention discloses a preparation method of a biaromatic compound represented by the structural formula III (see the specification for the structural formula and substituent), by adding a nonionic surfactant into the reaction system, the chlorinated aromatic hydrocarbon represented by the structural formula I and the structural formula The arylboronic acids shown in II undergo a Suzuki coupling reaction. The preparation method provided by the invention has the advantages of high reaction activity of chlorinated aromatic hydrocarbons, low cost of raw materials, mild reaction conditions and environmental protection. |
