Abstract

It is true to say that there is a greater need for green catalytic alternatives in fine chemicals manufacture in oxidation reactions. In contrast to reductions, oxidations are largely carried out with stoichiometric inorganic and organic oxidants such as chromium reagents, permanganate, Manganese dioxide and periodate. There is clearly a definite need for catalytic alternatives employing clean primary oxidants such as oxygen or hydrogen peroxide. Catalytic oxidation with O2 is widely used in the manufacture of bulk petrochemicals. The selective oxidation of alcohols to the corresponding carbonyl compounds is pivotal transformation in organic synthesis. There is a need for greener methodologies for these conversions, preferably employing O2 or H2O2 as clean oxidants and effective with a broad range of substrates. One method which is finding increasing application in the fine chemicals industry employs the stable free radical, TEMPO 2,2,6,6- tetramethylpiperidine-Noxyl) as a catalyst and NaOCl (household bleach) as the oxidant.
