Participants
| Role | Name | HCID | Charge |
|---|
| Reactant | 2-Nitrobenzoyl chloride | HCID 11875 | — |
| Reactant | 3-Penten-2-one, 4-[(trimethylsilyl)oxy]- | HCID 114632 | — |
| Product | 2,4-Pentanedione, 3-(2-nitrobenzoyl)- | HCID 5124893 | 21.3% |
Reaction Steps
A mixture of 2-nitrobenzoyl chloride (500 mg) with 4-trimethylsilanyloxy-pent-3-en-2-one (540 mg) was stirred at 140° C. for 5 min. The reaction solution was cooled to room temperature and was then purified by column chromatography using acetone-hexane to give 3-(2-nitro-benzoyl)-pentane-2,4-dione (143 mg, yield 20%).
