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.
