Abstract
An experimentally simple microwave‐assisted solvent‐free N‐arylation of primary amines with sodium tetraphenylborate or arylboronic acids, promoted by inexpensive cupric acetate, on the surface of KF–alumina is reported. The reaction is selective for mono‐N‐arylation, and a variety of functional groups are tolerated in the process.
