What is it about?

A supported dichromate oxidizing agent has been prepared. The support composed of a hybrid polymer-clay nanocomposite made by the direct interaction of poly(styrene‐co‐N‐methyl‐4‐vinylpyridinium) iodide with sodium montmorillonite (MMT) through ion exchange between sodium cations in MMT and pyridinium ions. EDX analysis showed the uniform distribution of Si in the polymer matrix.

Why is it important?

The hybride polymer–clay nanocomposite supported dichromate reagents was highly effective for the oxidation of saturated primary, secondary and benzylic alcohols to their corresponding aldehydic and ketonic compounds in addition to oxidation of quinol to the corresponding quinone. The most important observation was that there is no side product

Perspectives

We believe that this reagent can replace classical soluble dichromate reagent, due to its simple application, formation of single product, and ease of regeneration.
