Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Ethyl phenylacetate | HCID 7590 | — |
| Reactant | 2-Hydrazinylidene-1,2-diphenylethanone | HCID 79289 | — |
| Reactant | Sodium | HCID 5360545 | — |
| Solvent | Ethanol | HCID 702 | — |
| Product | HCID 3599665 | HCID 3599665 | 30% |
Reaction Steps
Sodium (11.5 g) was allowed to react with ethanol and then benzilmonohydrazone (120 g) and ethyl phenylacetate (84 g) were added and the reaction mixture heated at reflux for 3 hours. The reaction was quenched in water and the suspension acidified. The resulting precipitate was separated and refluxed with acetonitrile, cooled and separated by filtration to obtain 4,5,6-triphenyl-2H-pyridazin-3-one (30 percent yield), m.p. 290°-292° C.
