Abstract

Green chemistry offers signicant nancial and environmental advantages over traditional synthesis methods. It accomplishes this by subtly suggesting methods and tools. The present interest in green chemistry has proposed a further necessity for organic synthesis, where novel reaction conditions must locate, lowering the demand for hazardous ingredients or damaging organic solvents. These green approaches must improve selectivity, speed up reaction times, and facilitate product separation as compared to traditional routes. The rst synthesis of Schiff bases was recorded by Hugo Schiff in the 19th century (imines). A primary amine and an aldehyde are often combined to form a Schiff base, which is an aldehyde with an azomethine group (C=N group) instead of a C=O group. In order to determine the best approach that gives greater yields in less time while maintaining an environmentally friendly atmosphere, this study aims to concentrate on the green synthetic techniques utilised for Schiff bases synthesis. The review considered a number of environmentally friendly synthetics methods, among which microwave irradiation is considered to be the best, followed by ultrasonic, employing natural acids, and grinding techniques.
