Introduction :(1,2) ‘Green Chemistry’ is the new branch of chemistry which involves pulling together tools, techniques and technologies. It is helpful to chemists and chemical engineers in research, development and production for development of more eco-friendly and efficient products which may also have significant financial benefits. It is now going to become an essential tool in the field of synthetic chemistry. The development of Green Chemistry redefines the role of a solvent: “An ideal solvent facilitates the mass transfer but does not dissolve”. In addition, a desirable green solvent should be natural, nontoxic, cheap and readily available with additional benefits of aiding the reaction, separation or catalyst recycling. Of the various principles of green chemistry, the important one is maximizing the Atom Economy which evaluates the efficiency of chemical transformation and is calculated as
