Synthesis method of tri(tert-butyl-phenyl)sulfur bromide

Abstract

The invention belongs to the technical field of electronic materials, and discloses a synthesis method of tri(tert-butyl-phenyl)sulfur bromide. The method comprises the following steps: refluxing tert-butyl bromobenzene and magnesium powder in tetrahydrofuran to generate a Grignard reagent, dropwisely adding into a thionyl chloride tetrahydrofuran solution at low temperature, and carrying out reaction on the obtained di-p-tert-butyl-phenyl sulfoxide, the Grignard reagent and trimethylbromosilane at low temperature; and pouring the reaction solution into hydrobromic acid ice water, skimming the reaction solution, extracting the water phase with ethyl acetate and dichloromethane, respectively concentrating the dichloromethane phase and ethyl acetate phase, adding n-hexane into the concentrated ethyl acetate phase to precipitate a solid, and adding ethyl acetate into the dichloromethane phase to precipitate a solid, wherein the two solids are both the target product tri(tert-butyl-phenyl)sulfur bromide. The molecular formula of the product is C30H39BrS. The prepared product is white powder which can be easily dissolved in dichloroethane. The synthesis method has the advantages of low production cost, short preparation route and simple equipment, can easily implement industrial production, and can be widely used in electronic material production.
