Imidazolium fluorochromate

Oxidation of several primary aliphatic alcohols with potassium dichromate, pyri-dinium dichromate, quinolinium dichromate (QDC), imidazolium dichromate, nico-tinium dichromate, isonicotinium dichromate, pyridinium fluorochromate (PFC), quinolinium fluorochromate, imidazolium fluorochromate, pyridinium chlorochromate (PCC), quinolinium chlorochromate (QCC), and pyridinium bromochromate (PBC), in aqueous acetic acid and in the presence of perchloric acid, showed similar kinetics. The values of the reaction constants did not differ significantly, indicating operation of a common mechanism.1... [Pg.85]

Oxidations by imidazolium fluorochromate (IFC), pyridinium fluorochromate (PFC), quinolinium fluorochromate (QFC), quinaldinium fluorochroma (QnFC), and tripropy-lammonium fluorochromate (TPAFC) are also reported. [Pg.97]

Steric effects dominate in the oxidation of dialkyl, alkyl phenyl and benzal methyl phenyl sulfides to their sulfoxides by quinolinium fluorochromate (QFC) in aqueous acetic acid. QFC oxidation of phenoxyacetic acids has been smdied. Imidazolium dichromate oxidations of a-hydroxy acids have been smdied. ... [Pg.219]

Oxidative deoximation of aldo- and keto-oximes by tetraethylammonium chlorochro-mate in DMSO is first-order in oxime and oxidant, and the kinetic study was extended to 19 organic solvents. Similar kinetic behaviour was found for imidazolium fiuorochromate in the case of acetaldoxime, the same solvent survey was performed. Pyridinium fluorochromate as oxidant was also studied in DMSO. ... [Pg.21]
