Green chemistry with its twelve principals would like to see change in the convention synthesis and the use of less toxic starting materials. Green chemistry would like to increase the efficiency of synthetic method to use less toxic solvents, reduce the stages of synthetic routes and minimize waste as far as practically possible. In this way, chemical synthesis will be part of the effort for sustainable development. Microwave assisted synthesis has revolutionized chemicals synthesis. Small molecules can be built in a fraction of the time required by conventional methods. Alcohols are selectively oxidized to aldehyde using active cerium dioxide (CeO2) nanoparticles under solvent free using microwave irradiation. The complete conversion of the alcohols to their corresponding aldehydes was achieved successfully within 25-55 seconds of irradiation in microwave oven. The products of oxidation were characterized by TLC,IR and Tollen’s reagent test, which showed the characteristic results of the desired aldehydes.This method is found to be fast , green and a very easy procedure that could be applied for the oxidation of alcohols to aldehydes without further oxidation to carboxylic acids.
