Palladium‐Catalyzed Dehydrogenative Cross‐Couplings of Benzazoles with Azoles

Abstract

Different enough: Palladium-catalyzed cross-couplings of benzazoles with imidazoles, oxazoles, and thiazoles furnish unsymmetrical 2,2′-bisheteroaryls in high yield (see scheme). These oxidative CC bond formations use the selective cleavage of the CH bond at C2 in the two coupling partners and are robust enough to be conducted under normal air atmosphere.
