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 CC bond formations use the selective cleavage of the CH bond at C2 in the two coupling partners and are robust enough to be conducted under normal air atmosphere.
