Green Chemistry means design chemical processes to reduce generation of waste that effect on environment. We have to design methods which follows 12 Principles of green chemistry. Coumarins occupy an important place in the realm of natural products and synthetic organic chemistry. A highly efficient green process for synthesis of 3-Phenyl Coumarins from salicylaldehydes and phenyl acetyl chlorides in presence of N-methyl imidazole as green solvent & catalyst using microwave chemistry was developed and prepared various derivatives. The method is simple giving high yield of pure product and recycle all reagents.

Salicylaldehyde, N-Methyl imidazole, Phenyl acetyl chloride, Sodium Hydroxide, Bromine, Chlorine, Acetic acid, Calcium Nitrate tetra hydrate, Microwave oven CATA 2R Model, Ethyl alcohol, Isopropyl alcohol and Ethyl acetate.
