3,5-Dichloropentan-2-one → 3-Thiocyanato-5-chloro-2-pentanone
Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | 3,5-Dichloropentan-2-one | HCID 94032 | — |
| Reactant | Sodium thiocyanate | HCID 516871 | — |
| Solvent | Ethanol | HCID 702 | — |
| Product | 3-Thiocyanato-5-chloro-2-pentanone | HCID 10877693 | 87% |
Reaction Steps
A solution of 7.8 g (0.05 moles) of 3,5-dichloro-2-pentanone with 4.15 g (0.051 moles) of sodium rhodanide in 50 cm3 of ethanol is boiled for 2 hours under stirring. Then the procedure described in Example 1 is followed. 7.7 g (87%) of 3-thiocyanato-5-chloro-2-pentanone are obtained, which is identical in all respect with the product of Example 1 after distillation.
