Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Lithium Hydroxide | HCID 3939 | — |
| Reactant | Ethyl trans-2-phenylcyclopropanecarboxylate | HCID 252496 | — |
| Solvent | Ethanol | HCID 702 | — |
| Product | trans-2-Phenylcyclopropanecarboxylic acid | HCID 237413 | 90.1% |
Reaction Steps
To a stirred mixture of 33 (153 g, 804.25 mmol, 1.00 equiv) in EtOH (1 L) was added 1M aq. LiOH (1 L), and the resultant solution was stirred at reflux for 1 h. Volatile solvent was removed under reduced pressure and the residue diluted with EtOAc (1.5 L). The organic phase was washed with water (3×1 L) and brine (1×1 L), dried (Na2SO4), filtered and concentrated in vacuo to afford 117.5 g (90%) of trans-2-phenylcyclopropane-1-carboxylic acid (35) as a white solid.
