<i>N</i>-Amidation by Copper-Mediated Cross-Coupling of Organostannanes or Boronic Acids with <i>O</i>-Acetyl Hydroxamic Acids

Abstract

A general nonoxidative N-amidation of organostannanes and boronic acids has been developed. Under nonbasic conditions a wide variety of aryl, alkenyl, and heteroaryl organostannanes and boronic acids couple efficiently with O-acetyl hydroxamic acids in the presence of Cu(I) sources.
