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.

Key words: thionyl chloride;coupling reaction;benzamides;benzoic acid; solvent free.
