1,2-Difluoro-4-nitrobenzene → 2-Fluoro-4-nitrothioanisole
Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | 1,2-Difluoro-4-nitrobenzene | HCID 123053 | — |
| Reactant | Sodium methanethiolate | HCID 4378561 | — |
| Solvent | Water | HCID 962 | — |
| Product | 2-Fluoro-4-nitrothioanisole | HCID 22592505 | 66.2% |
Reaction Steps
A mixture of 3,4-difluoro-nitrobenzene (25 g, 0.157 mol) and sodium methanethiolate (10.5 g, 0.15 mol) was stirred at room temperature overnight. The reaction mixture was poured into water and extracted twice with ether. The extracts were combined, washed with water (twice) and brine, dried (sodium sulfate), filtered, evaporated, and purified by column chromatography, eluting with 17% dichloromethane/hexanes to give 2-fluoro-1-methylsulfanyl-4-nitro-benzene (18.6 g, 63%).
