Propylene Chlorohydrin → 2-Chloropropyl 3-oxobutanoate
Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Propylene Chlorohydrin | HCID 6566 | — |
| Reactant | Diketene | HCID 12661 | — |
| Reactant | Sodium Acetate | HCID 517045 | — |
| Product | 2-Chloropropyl 3-oxobutanoate | HCID 13231365 | 69.2% |
Reaction Steps
0.7 g of sodium acetate was added to 7.5 g of 2-chloropropanol, to which 7.4 g of diketene was added dropwise with stirring while the reaction temperature was maintained at 40°-50° C. The reaction mixture was stirred at room temperature for an additional 2 hours and then worked up in the manner described in Referential Example 4. The resulting crude product was purified by distillation to obtain 9.8 g of 2-chloropropyl acetoacetate.
