One-Pot Synthesis of Organic Disulfides (Disulfanes) from Alkyl Halides Using Sodium Sulfide Trihydrate and Hexachloroethane or Carbon Tetrachloride in the Poly(ethylene glycol) (PEG-200)

Symmetric disulfides are produced by treating their corresponding organic halides including benzylic, allylic, primary and secondary halides with Na 2 S·3H 2 O and C 2 Cl 6 or CCl 4 in PEG-200 at room temperature in high yields.
