Abstract
A novel, simple, green, one pot and practical synthetic method is described for the preparation of phthalimide derivatives through a condensation reaction between of 2-formylbenzoic acid and aniline in the presence of Et3N as base and S8 (Octasulfur) as oxidant in solvent free condition. This one-pot protocol provides these valuable desired compounds under mild conditions with excellent efficiency by using simple available starting materials.
