The invention discloses an efficient halogenation synthesis method of an aryl halide. The synthesis method comprises performing a halogenation reaction on an aromatic ring compound in the presence of a catalyst (the catalyst is sulfoxide or nitrogen oxide), a halogenation reagent and a solvent, Aryl halides are obtained. In the present invention, in the presence of a catalyst (the catalyst is sulfoxide or nitrogen oxide), a halogenating agent and a solvent, a very useful aryl halide can be obtained with high activity and selectivity by performing efficient halogenation on the aromatic ring. . By adopting the method of the invention, the aryl halide can be synthesized efficiently, and it will have wide application prospects in actual production. |
