Crystal structure and Hirshfeld surface analysis of 1,2-ethylene-bis (para-methyl pyridinium) dichromate as a new selective and mild agent in oxidation of alcohols

1,2-Ethylene-bis(para-methyl pyridinium) dichromate, (C14H18N2)[Cr2O7], is used as a new oxidizing agent in conversion of some alcohols to their corresponding carbonyl compounds in CH3 CN solvent and also under solvent-free conditions. In both procedures, high conversion percentages are observed. However, a much shorter reaction time is achieved in solvent-free conditions. For allylic alcohols, the C=C bond is not oxidized and the examined saturated alcohol in this work (i.e. cyclo-hexanol) remains intact, which illustrates the mild nature of reagent used.
