microwave assisted oxidation coupling of thiols to symmetrical disulfides with tripropylammonium fluorochromate (vi) (tpafc)

tripropylammonium fluorochromate(vi) (tpafc), is an efficient and new reagent, which isprepared easily and oxidizes thiols to the corresponding disulfides, quickly. the reactions areperformed cleanly and are controlled to stop at the disulfide stage, without over-oxidation andside products. coupling of thiols to their corresponding disulfides, are studied in solution atroom temperature and in solution under microwave radiation. the easy procedure, simple workup,short reaction times, and excellent yields, are another advantages of this reagent.
