Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Isopropenyl acetate | HCID 7916 | — |
| Reactant | 2-Methyl-3-oxopentanal | HCID 12712037 | — |
| Catalyst | Sulfuric Acid | HCID 1118 | — |
| Product | HCID 4002931 | HCID 4002931 | 70.5% |
Reaction Steps
A mixture of 11.4 g of 2-formyl-3-pentanone and 17 g of isopropenyl acetate was brought to reflux in the presence of 0.1 g of sulfuric acid. After removal of the acetone formed at ambient pressure, the desired product was distilled under vacuum. In this manner 11 g of 1-acetoxy-2-methyl-1-pentene-3-one was obtained under conditions of 104° C. and 16 mm of mercury, which is a yield of 70%.
