Copper-Catalyzed N-Arylation of Amines/Amides in Poly(ethylene glycol) as Recyclable Solvent Medium

Abstract

The Buchwald N-arylation of amines and amides is achieved efficiently in PEG (400 Daltons) as solvent medium. The solvent and catalyst recyclability is studied. Interestingly amides underwent N-arylation with better yields.

Key words

N-arylation - copper iodide - poly(ethylene glycol) - reusability
