Imines are precursors for synthesis of ligands, amines and heterocyclic compounds. Though various catalysts have been developed for carbonyl-primary amine condensation reactions. Solvents and catalysts often prolongs workup process. A concise and solvent-free procedure for synthesis of Schiff bases with aromatic aldehydes and primary amines has been developed. Conventional methods require azeotropic distillation and using drying agents. This is not only environmentally degrading but also time-consuming. In this poster we will present a concise method which will eliminate the need of solvent. The method is  designed for energy efficiency by incorporating microwaves to supply heat and evaporate water.<br/>
