Phosphorus oxychloride (570.02 g) was added to sodium 4-pentene-1-sulfonate (199.18 g) at room temperature. After reflux for 3 hours, the solution was cooled in an ice bath. The reaction solution was added gradually to a large amount of ice water. After extraction with diethyl ether, the organic layer was washed with brine, dried with magnesium sulfate, and concentrated under reduced pressure to obtain 4-pentene-1-sulfonyl chloride (106.31 g) as dark brown oil.
