A novel NCN type palladium pincer complex based on the porphyrin backbone was synthesized. The palladium atom bound to the meso-carbon of the porphyrin core was effectively supported by two imidazolyl groups. The product was characterized by spectroscopic and X-ray diffraction analysis. The structure of the porphyrinic macrocycle was revealed to be highly distorted by the coordination of the outer palladium center. The degree of deformation was found to be even larger than the analogous palladium pincer complexes in which pyridine groups were employed as the supporting ligands. The complex exhibited high catalytic activity in the Mizoroki-Heck reaction of iodobenzene with butyl acrylate with 0.005% of the catalyst loading.
