Hydroamination of terminal alkynes with secondary amines catalyzed by copper: regioselective access to amines
2015
A simple and convenient copper-catalyzed hydroamination of arylacetylenes with secondary amines has been performed giving a simple access to aliphatic amines after reduction of the hydroaminated products (E-enamines). Here we described a mild catalytic system utilizing CuCN precatalyst without any additive ligands in a solvent-free system.
