ABSTRACT
Schiff bases and their metal complexes are widely used in both industrial as well as in the biological significance. Schiff bases are formed by the condensation reaction of an amino group with the carbonyl compounds, which leads to the formation of imide groups (–C=N–). In the recent era, the macrocyclic ligands of Schiff bases in the inorganic chemistry are the motivating topic and continuously gaining popularity in the research for younger scientists due to their versatile applications in industries such as polymer, dyes as well as pharmaceutical. In this chapter, we focused on the greener approach to synthesize the Schiff base legends. Tremendously, well organized and simple green synthesis method of Schiff bases and their metal complexes are discussed in this chapter. The significance of green chemistry and efficient, practical techniques like microwave irradiation, water-based reaction, UV radiation, and simple mortal—pastel method (mechanochemistry), Ultrasound sonication method, sonication (sonochemistry), along with few conventional techniques were explored and discussed. Few of the characterization methods have also been discussed, such as 496NMR and physicochemical studies. This chapter compiles the different aspects and principles of green chemistry in the Schiff base ligands and their metal complexes.
