Solvent-mediated One-pot Synthesis of Cyclic N -Substituted Imides.

The article presents a study on the organic synthesis of cyclic nitrogen (N)-substituted imides. It states that acetic acid was used to produce amic acids from cyclic anhydrides and aniline. It mentions that amine has undergone acetic acid and cyclic anhydride treatment within 10 minutes and then sulfuric acid treatment for 45 minutes. It says that proton nuclear magnetic resonance (¹H NMR) spectrocopy and infrared spectroscopy were used in the study. It adds that the products of the experiment underwent purification by silica gel column chromatography with the use of choloform.
