Efficient selective oxidation of organic substrates using pyridinum sulfonate halochromate under solvent-free conditions and microwave irradiation: Experimental and theoretical study

A convenient and rapid method has been developed for the selective oxidation of several types of alcohols to related carbonyl compounds under solvent-free conditions. In this study, the authors report the microwave-assisted selective oxidation of alcohols and a number of organic compounds with pyridinum sulfonate chlorochromate (PSCC) and pyridinum sulfonate fluorochromate (PSFC). The density functional theory calculations were made at B3LYP/6-31G* levels of theory and thermodynamic data supported the proposed mechanism involving formation of a halochromate ester, which showed that PSFC should be a more capable oxidant than PSCC. The oxidation products are easily obtained in short reaction time with good yields.

Shaken not stirred; Oxidation of alcohols with sodium dichromate

Efficient and selective oxidation of primary alcohols to the corresponding aldehydes with sodium dichromate at room temperature under solvent-free conditions by shaking is described. This new procedure can also successfully oxidise secondary alcohols.
