ligands are reported to be highly efficient catalysts for C–C coupling reactions, giving excellent yields with low catalyst loading.1–8 A relatively new amino pincer palladium complex has been reported by Frech for C–C bond formation via the Heck, Sonogashira, Stille, Hiyama and Suzuki-Miyaura reactions.3–7 A myriad of palladium complexes exist to promote these C–C bond forming processes.9 However
