Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Veratraldehyde | HCID 8419 | — |
| Reactant | 1-(4-(2-Propen-1-yloxy)phenyl)ethanone | HCID 95969 | — |
| Solvent | Ethanol | HCID 702 | — |
| Product | 3,4-Dimethoxy-4'-allyloxychalcone | HCID 54481784 | 99% |
Reaction Steps
1.76 g (10 mmol) of 4-allyloxyacetophenone and 1.66 g (10 mmol) of 3,4-dimethoxy-benzaldehyde were under a dry inert atmosphere (argon) dissolved in 10 ml dry ethanol and the solution was stirred for 18 h. The solution was filtered to give 3.0 g (99%) of 3,4-dimethoxy-4′-prop-2-enyloxychalcone which was recrystallized from ethanol, m.p. 74.5-75° C.
