Copper-catalyzed, oxidative sp2 C-H cyanation: Facile synthesis of aromatic carbonitriles

Cu(OAc)2-catalyzed regioselective oxidative C-H cyanation of two different types of aromatics was described, providing facile access to functionalized heterocycles in good yields. Control experiments suggest the copper chelation-assisted oxidative C-H activation mechanism. ARKAT-USA, Inc.
