A Pd(0)-catalyzed double C-N coupling of 5,5′-dibromo-2,2′-bithiazoles with (het)arylamines and subsequent in situ Ag2O-mediated oxidation provides access to cross-conjugated quinoidal 5,5′-diarylimino-2,2′-bithiazoles in moderate to high yield. The highly colored quinoidal 2,2′-bithiazoles were studied by UV/vis spectroscopy, cyclic voltammetry and computational methods. © 2016 American Chemical Society.
