Abstract
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.
