Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Phosphorus pentachloride | HCID 24819 | — |
| Reactant | 4-{[(Benzyloxy)carbonyl]oxy}benzoic acid | HCID 17914102 | — |
| Solvent | Diethyl Ether | HCID 3283 | — |
| Product | 4-Carbobenzoxyoxybenzoyl chloride | HCID 19734054 | 57.7% |
Reaction Steps
A solution of 27 m moles (7.3 g) of the above 4-carbobenzoxyoxybenzoic acid and 27 m moles (5.6 g) of phosphorus pentachloride in 50 ml of ether was stirred for 24 hours at room temperature. After the reaction, deetherizing was carried out, and the obtained crystal was recrystallized from hexane, to obtain 4.5 g of 4-carbobenzoxyoxybenzoyl chloride [m.p. 65.5°-67.4° C⟧ (yield: 57%)
