Abstract

A simple copper salt catalyzed N-arylation reaction with arylboronic acids is reported. In the presence of a catalytic amount of a simple copper salt, the coupling of arylboronic acids with imides was performed in MeOH to give N-arylimides in excellent yields; a variety of amines, amides and sulfonamides could also be successfully coupled with arylboronic acids to give corresponding N-arylated products in moderate yields.

Key words

N-arylation - copper salt - boronic acid - coupling - Ullmann reaction
