摘要：

Pd halide and hydride complexes of a new PNP pincer ligand with a central diarylamido moiety can be prepared via N-H cleavage in a neutral amine / diphosphine PNP ligand. The solid-state structure of (PNP)PdCl shows a meridional PNP ligand about an approximately square-planar Pd center. (PNP)PdH hydrodehalogenates alkyl and certain aryl halides, while (PNP)PdX (X = Cl, I, H, OAc) complexes catalyze Heck coupling of ethyl acrylate with aryl halides.
