Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | 2-Methylbenzenesulfonic acid | HCID 6925 | — |
| Reactant | 1-Diazopentan-2-one | HCID 53766571 | — |
| Solvent | Chloroform | HCID 6212 | — |
| Product | 2-Oxopentyl-o-toluene sulfonate | HCID 12821610 | 59.9% |
Reaction Steps
A 1.0 g quantity of 1-diazo-2-pentanone is dissolved in 50 ml of chloroform, and 2.2 g of o-toluene-sulfonic acid is slowly added to the solution. The same procedure as in Example 1 is thereafter repeated to afford 1.37 g of 2-oxopentyl-o-toluene sulfonate in the form of a transparent colorless oil (Compound 29). Yield 59.9%.
