Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Triphenylphosphine | HCID 11776 | — |
| Reactant | Ethyl 2-(bromomethyl)benzoate | HCID 11032082 | — |
| Solvent | Tetrahydrofuran | HCID 8028 | — |
| Product | 2-Ethoxycarbonylbenzyltriphenylphosphonium bromide | HCID 19092713 | 56.3% |
Reaction Steps
A solution of ethyl 2-bromomethylbenzoate (1.00 g) in tetrahydrofuran (10.0 ml) and triphenylphosphine (1.21 g) was heated under reflux for 8 hours. After being cooled, the resulting precipitates were collected by filtration and washed with tetrahydrofuran to give 2-ethoxycarbonylbenzyltriphenylphosphonium bromide (1.17 g).
