title: Copper-catalyzed direct amination of ortho-functionalized haloarenes with sodium azide as the amino source.
abstract: A simple copper-catalyzed direct amination of ortho-functionalized haloarenes (2-halobenzoic acid, 2-halobenzamide, and N-(2-bromophenyl)acetamide derivatives) has been developed with use of NaN(3) as the amino source in ethanol, and the corresponding ortho-functionalized aromatic amines were synthesized in good to excellent yields. The protocol undergoes one-pot Ullmann-type coupling of ortho-functionalized haloarenes with NaN(3) to lead to ortho-functionalized azidoarenes, followed by reduction with ethanol.
