Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Phosphorus pentachloride | HCID 24819 | — |
| Reactant | 2,2,3,3-Tetrafluoro-3-methoxypropanoic acid | HCID 13328907 | — |
| Product | 3-Methoxy-2,2,3,3-tetrafluoropropionyl chloride | HCID 12846026 | 95.2% |
Reaction Steps
A mixture of 47.4 g 3-methoxytetrafluoropropionic acid and 67.3 g phosphorous pentachloride was heated and the contents distilled to obtain a pale yellow liquid boiling to 102°. Redistillation of this liquid yielded 49.8 g (95.2%) 3-methoxytetrafluoropropionyl chloride, b.p. 84°-86°.
