Abstract: We report the Sonogashira cross-coupling of aryl ammonium salts catalyzed by air- and moisture-stable [Pd(NHC)(3-CF3-An)Cl2] (An = aniline). This highly active Pd(II)-NHC complex features broad scope and excellent C-N activation selectivity in the challenging alkynylative… read more here.
