Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Coumarin | HCID 323 | — |
| Catalyst | Platinum oxide (PtO) | HCID 82844 | — |
| Solvent | Ethyl Acetate | HCID 8857 | — |
| Product | Dihydrocoumarin | HCID 660 | — |
Reaction Steps
Coumarin (30 g, 0.205 moles) is reduced on the Parr apparatus in 200 ml ethyl acetate with 1 g platinum oxide at 40 psi. When the uptake ceased (ca. 1 hr.) the catalyst is removed by filtration and the filtrate evaporated to give a quantitate yield of dihydrocoumarin.
