Background: Green Chemistry is an interdisciplinary science or it can also be explained
as a branch of chemistry. It is generally described as the chemistry to aim to synthesize chemical
compounds to trim down the utilization of harmful chemicals proposed by the Environmental Protection
Agency (EPA). Recently, the plan of academicians, researchers, industrialists is to generate
greener and more efficient methodologies to carry out various organic syntheses.
Objective: In the present scenario, green chemistry utilizes the raw materials economically, minimizes
the waste and prevents the uses of harmful or hazardous chemicals to make the organic reactions
simple and efficient.
Conclusion: Microwave technique is a new, simple and efficient technology which opens new
prospects to the chemists to carry out various organic and inorganic reactions, which are difficult
via conventional methodology. It is used to decrease the duration of time to carry various organic
transformation along with maximum yield, minimum by-products, minimum energy utilization,
less manpower etc. e.g. various famous organic reactions have been carried out by various research
groups like Aldol condensation, Knoevenagel condensation, Beckmann rearrangement, Vilsmeier
reaction, Perkin reaction, Benzil-Benzilic acid rearrangement, Fischer cyclization, Mannich reaction,
Claisen–Schmidt condensation, etc. Further, reduction, oxidation, coupling, condensation reaction
were also performed using microwave technology.
