Formation of Acyl Chlorides
- Due to the increased reactivity of acyl chlorides compared to carboxylic acids, they are often used as starting compounds in organic reactions
- Acyl chlorides are compounds that contain an -COCl functional group and can be prepared from the reaction of carboxylic acids with:
- Liquid sulfur dichloride oxide (SOCl2)
- Propanoyl chloride can this way be prepared from propanoic acid using the reaction above
