A 1D palladium coordination polymer and its catalytic activity in microwave-assisted Sonogashira reactions

Abstract

A palladium coordination polymer, [Pd(dppp)(L)](OTf)2·(H2O)] (1) (dppp = 1,3-bis(diphenylphosphino)propane), was prepared from a bipyridine-type ligand (L = (4-py)–CH = N–C10H6–N = CH–(4-py)) and [Pd(dppp)](OTf)2. An X-ray diffraction study showed that it has a one-dimensional zigzag chain structure and the triflate ions act as counterions. Compound 1 exhibited Sonogashira coupling reactivity in air under microwave conditions.
