A kind of preparation method of 4-phenylmercapto thiophenol |
| abstract |
The invention provides a preparation method of 4-phenylmercaptothiophenol. Utilize diphenyl sulfide and brominated reagent to prepare 4-brominated diphenyl sulfide through bromination reaction, the obtained 4-brominated diphenyl sulfide is subjected to Grignard reaction to obtain corresponding Grignard reagent, and then reacts with sulfur and acidifies to prepare 4-brominated diphenyl sulfide. Phenylmercaptothiophenol. The raw materials used in the invention are cheap and easy to obtain, the operation process is simple, the reaction conditions are easy to realize, and the cost is low; |
