Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | 1,3-Benzodioxole-5-carboxylic acid | HCID 7196 | — |
| Reactant | Thionyl Chloride | HCID 24386 | — |
| Product | 1,3-Benzodioxole-5-carbonyl chloride | HCID 2734749 | — |
Reaction Steps
20 g (0.12 mole) of piperonylic acid are suspended in 170 ml of thionyl chloride and refluxed for 2 hours. The solution is concentrated under reduced pressure. The residual oil crystallizes immediately after the addition of petroleum ether. The crystals are spun and washed with petroleum ether.
