text: Sulfenyl chlorides are typically prepared by chlorination of disulfides:   This reaction is sometimes called the Zincke disulfide reaction, in recognition of Theodor Zincke. 
  Some thioethers () with electron-withdrawing substituents undergo chlorinolysis of a  bond to afford the sulfenyl chloride.
  In a variation on the Reed reaction, sulfur dichloride displaces hydrogen under UV light.
