چکیده
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.

Oxidative coupling of thiols to disulfides in solution radiation with Trimethylammonium Fluorochromate(VI), [(CH3)3NH[CrO3F], 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.

In this study, silica nanoparticles were used as support to prepare a new heterogeneous catalyst system for application in organic reactions. The reaction of silica nanoparticles with sodium 2-bromoethane-1-sulfonate resulted in the connection of a sulfonic acid group on the surface of silica nanoparticles (NSESA). The synthetic catalyst system was characterized using different microscopic and ...

Surface of mesostructured silica, KIT-6, was modified by grafting 3-aminopropyl-triethoxysilane (APTES) to have the positive charge, and thus, to provide sites for the immobilization of H3PW12O40 (PW12). This modified-nanosized mesoporous silica (PW12-APTES@ KIT-6) was characterized by FTIR, XRD, BET and TEM. The oxidation of sulfides occurs effectively and selectively with H2O2 as the oxidant...
