摘要：
Silica gel absorbed trimethylammonium fluorochromate (VI), (TriMAFC), (CH3)(3)NHCrO3F and trimethylammonium chlorochromate(VI), (TriMACC), (CH3)(3)NHCrO3Cl are efficient and new reagents, which prepare easily and oxidize thiols to the corresponding disulfides quickly. The reactions perform cleanly and controlled to stop at the disulfide stage without over-oxidation side products. The easy procedure, simple work-up, short reaction times and excellent yields are another advantages of these reagents.
