A copper-catalyzed dehydrogenative cross-coupling of benzothiazoles with thiazoles and polyfluoroarene under mild reaction conditions is described. This protocol provides a straightforward and operationally simple method for the synthesis of the 2,2'-linkage of thiazoles and 2-polyfluoroarylthiazoles of interest in life and material sciences.

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.
