Polyethylene Glycol as a Nonionic Liquid Solvent for the Synthesis of N-Alkyl and N-Arylimides

Abstract

Abstract Polyethylene glycol (PEG) an inexpensive, nontoxic, environmentally friendly reaction medium for the synthesis of N-alkyl and N-arylphthalimides to afford the corresponding adducts in excellent yields under mild reaction conditions. The use of PEG avoids the use of acidic or basic catalysts, and moreover PEG could be recovered and reused.
