The oxidation of Mandelic Acids (MA) to the corresponding oxoacids with tripropylammonium fluorochromate (TriPAFC) in aqueous acetic acid has been studied. The reaction is first order with respect to [TriPAFC], [MA] and [H+]. The oxidation of α-deuteriomandelic acid shows the presence of a primary ki...

N-Methylbenzylammonium fluorochromate(VI) (MBAFC) is easily synthesized by addition of N-methylbenzylamine to an aqueous solution of CrO3 and HF. MBAFC shows selectivity in the oxidation of aryl alcohols to their corresponding aldehydes and ketones under mild conditions. The durability, ease of work up and efficiency of MBAFC are considerably increased upon its absorption on silica gel.

A mild and efficient method for the oxidative coupling of thiols by trimethylammonium fluorochromate(TriMFC) in solution is reported. Trimethylammonium fluorochromate is efficient and new reagent, whichprepares easily and oxidizes thiols to the corresponding disulfides quickly. The reactions perform cleanly andcontrolled to stop at the disulfide stage without over-oxidation side products.
