Abstract


A new method of thionyl chloride induced convenient synthesis of novel benzamides under solvent free conditions has been developed using benzoic acid and amines. The benzamides were synthesized through a coupling reaction of benzoic acid and different amines using thionyl chloride at room temperature. The abovementioned technique assists in the preparation of substituted benzamides which were obtained in good yields within 2-4 h using conventional heating. The developed method is flexible, economic, environment friendly; also is catalyst, ligand and solvent free and has major importance in industry and laboratory.
