Phosphorus pentachloride → HCID 54434434, compound

Participants

Reaction Steps

To an ice-cold stirred suspension of 2-dichloroacetoxyimino-2-(fur-2yl)acetic acid (1.5 g) in dry methylene chloride (70 mls) was added dropwise a freshly prepared solution of phosphorus pentachloride (1.0 equiv.) in methylene chloride. When solution was complete the solvent was evaporated at low temperature and the residual oil azeotroped with benzene to give 2-dichloroacetoxyimino-2(fur-2yl)acetyl chloride (syn-isomer) as a pale yellow oil which was used directly.
