Abstract
Present research work demonstrates the use of garlic as natural biocatalyst for green synthesis of a series of Schiff bases which are an important class of pharmaceutically important compounds, employing p-toluidine and variety of aromatic aldehydes as reactants. The products were obtained with good percentage of yield by simply grinding the reactants together with pestle in a mortar in presence of a piece of garlic in a completely solvent free condition. The synthesized crude products were purified by recrystallization from hot ethanol to obtain pure Schiff bases which were characterized by melting point, FTIR, 1H-NMR and 13C-NMR. Through this work, a very simple, eco-friendly, effective, economic and new methodology is developed for synthesis of Schiff bases.
