Simple Heteropoly Acids as Water-Tolerant Catalysts in the Oxidation of Alcohols with 34% Hydrogen Peroxide, A Mechanistic Approach

摘要

Simple Keggin type tungsten and molybdenum heteropoly acids, H3PW12O40 and H3PMo12O40, were used as water-tolerant catalysts for the oxidation of alcohols with 34% hydrogen peroxide in normal drinking water. According to our findings, H3PW12O40 may be used as a simple, effective, and cheap catalyst for this type of transformation in normal drinking water with excellent yields. Effects of different solvents at 25-80 oC and changing concentration of catalyst and substrate on the reaction progress were also studied.
