Efficient oxidation of thiols to disulfides by triethylammonium halochromates (C2H5)3NH+[CrO3X]-, (X=F, Cl) under microwave irradiation

Mohammad Kazem Mohammadi

Triethylammonium fluorochromate (TEAFC) and Triethylammonium chlorochromate (TEACC) are new efficient reagents, which were easily prepared and oxidized thiols to the corresponding disulfides swiftly. The reactions perform cleanly and terminate simultaneously at the disulfide stage without any side products. Oxidizing of some thiols to their corresponding disulfides was studied in solution at room temperature and under microwave radiation. The easy procedure, simple work-up, short reaction times, and excellent yields, were advantages of these reagents.
