Solventless Synthesis of Imines Derived from Diphenyldisulphide Diamine or p-Vanillin
A solventless synthesis can reduce environmental contamination and can be more convenient than solvent-based synthesis. A series of Schiff bases were synthesized in high yield > 90% under solvent free conditions with negligible waste. All the synthesized products were characterized on the basis of spectral, elemental analysis and melting points and were compared with the data of the prouducts obtained from classical method
