Abstract
A copper-catalyzed
electrophilic amination of aryl and heteroaryl
aluminums with <i>N</i>,<i>N</i>-dialkyl-<i>O</i>-benzoyl hydroxylamines that affords the corresponding
anilines in good yields has been developed. The catalytic reaction
proceeds very smoothly under mild conditions and exhibits good substrate
scope. Moreover, the developed catalytic system is also well suited
for heteroaryl aluminum nucleophiles, providing facile access to heteroaryl
amines
