Sulfuryl chloride → Ethyl 2-chloro-3-oxopentanoate

Participants

Reaction Steps

Ethyl 3-oxopentanoate, 20.0 grams (0.175 mole), was stirred at ambient temperature, and 23.6 grams (0.175 mole) of sulfuryl chloride was added dropwise during a 20 minute period. Upon completion of addition, the reaction mixture was stirred for about 16 hours. The reaction mixture was then distilled under reduced pressure, yielding 23.3 grams of ethyl 2-chloro-3-oxopentanoate; bp 100°-103° C. at 21mm.
