Future Trends in Green Synthesis

Green approach is an advance technique of synthetic chemistry. It opens up a new vista of modified version of known synthetic reactions in a newer way with associated enlarged potentiality accompanied by sustainability. Revolutionary measures against solvent-based reaction have been invited in green routes. Organic solvents have been substituted by non-organic media in organic synthetic reactions to overcome the hazard of volatile organic solvents and to preserve the greenness of the reactions, following green principles, supported by green matrices. This chapter illustrates the successive green revolutionary measures in solvent-based organic chemistry followed by solvent-free synthetic routes and their future trends in a nut shell.
