Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | 4-(4-Chlorobenzoyl)benzyl bromide | HCID 9839651 | — |
| Reactant | Methylmercaptan sodium | HCID 45051789 | — |
| Solvent | Methanol | HCID 887 | — |
| Product | 4-Chloro-4'-methylthiomethylbenzophenone | HCID 19689365 | 83% |
Reaction Steps
4-bromomethyl-4'-chlorobenzophenone (3.1 g) and 15% methylmercaptan-sodium aqueous solution (5.6 g) were added to methanol (150 ml), and the mixture was stirred for 30 minutes under reflux. The reaction mixture was concentrated and extracted with ethyl acetate. The ethyl acetate layer was washed with water and then dried over anhydrous magnesium sulfate. Ethyl acetate was distilled off under reduced pressure. The residual solid was washed with n-hexane to obtain the desired product (2.3 g, melting point: 59° to 61° C., yield: 83%).
