Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | 3,5-Dichloropentan-2-one | HCID 94032 | — |
| Reactant | Amthio | HCID 13417437 | — |
| Solvent | Methyl Ethyl Ketone | HCID 6569 | — |
| Product | 3-Thiocyanato-5-chloro-2-pentanone | HCID 10877693 | 95.7% |
Reaction Steps
A suspension of 7.8 g (0.05 moles) of 3,5-dichloro-2-pentanone with 3.9 g (0.051 moles) of ammonium rhodanide in 50 cm3 of methyl-ethyl-ketone is boiled for 1 hour under stirring. Then the procedure described in Example 1 is followed. 8.5 g (95.5%) of 3-thiocyanato-5-chloro-2-pentanone are obtained, which after distillation is identical in all respect with the product of Example 1.
