Solvent-free microwave reactions towards significant organic transformations: A green approach

The electromagnetic radiation from microwave irradiation has been widely employed as a heating source in various significant organic transformations over the past two decades. The method, without adding any solvent while tied to microwave treatment, is acompletely environmentally benign platform with conspicuous advancements and has resulted in copious advantages with regards to rate of reaction and yield of the products compared to the other classical techniques. Therefore, in this review, we have attempted to summarize some recently developed organic reactions based on microwave-radiated solvent-free protocols, which would be very efficient for academic and industrial use without affecting the principles of green chemistry.
