A simple and efficient procedure for aerobic oxidation of thiols into symmetric disulfides using Na2S4O6 as catalyst in situ generated by reacting Na2S2O3 with I2 in poly ethylene glycol (PEG-200) has been introduced. Using this catalyst system,convenient protocol for one-pot achievement of symmetric disulfides via aerobic oxidation of thiols in situ generated by reacting alkyl halides with thiourea is introduced.
