MICROWAVE ASSISTED ORGANIC SYNTHESIS-A POTENTIAL TOOL FOR GREEN CHEMISTRY
A. Gopi Reddy*, J. Lavanya and D. Amitha
ABSTRACT
Microwave radiation, an electromagnetic radiation, is widely used as a source of heating in organic synthesis. Microwave assisted organic synthesis (MAOS) has emerged as a new “lead” in organic synthesis. The basic mechanisms observed in microwave assisted synthesis are dipolar polarization and conduction. The technique offers simple, clean, fast, efficient, and economic for the synthesis of a large number of organic molecules. Green chemistry efficiently utilizes raw materials, eliminates waste, and avoids the use of toxic or hazardous reagents and solvents in the manufacture and application of chemical products. Microwave assisted technique opens up new opportunities to the synthetic chemist in the form of new reactions that are not feasible using conventional heating and serve a flexible platform for chemical reactions. Over the past five years there has been a dramatic uptake in the use of microwaves as an energy source to promote synthetic transformations. Microwave-assisted synthesis is clearly a method by which the laboratory chemist can achieve goals in a fraction of the time as compared to traditional conductive heating methods. Reaction times in the best cases have been reduced from hours or days to minutes. In the present article an attempt was made to focus on what is microwave assisted synthesis, how is it generated and what importance may it have.
