摘要：

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 Ci-C bond formations use the selective cleavage of the Ci-H bond at C2 in the two coupling partners and are robust enough to be conducted under normal air atmosphere. © 2011 WILEY-VCH Verlag GmbH & Co.
