Oxidation of Benzylic Alcohols with Urea Hydrogen Peroxide/Calcium Chloride in PEGDME250

However, most of the aforementionedreagent systems are generally exotic, toxic, and expensivewhich limit their practical applications. In addition, hydro-gen peroxide is considered to be an ideal green oxidant forthe oxidation reactions of alcohol s due to its low toxicity andready availability. However, utilization of hydrogen peroxidefor the alcohol oxidation reactions generally required use oftransition metal based peroxo-complexes as activators.
