  Preparation of palladium complexes of 1,3-di(2-pyridyl)propane derivatives and their use in norbornene polymerization

  摘要：

  A variety of neutral palladium(II) complexes [Pd(L-L)Cl-2] containing 1,3-di(2-pyridyl)propane (1), 1,3-bis(2-pyridyl)-2-pentylpropane (2), 1,3-bis(2-pyridyl)-2-phenylpropane (3a), 1,3-bis(2-pyridyl)-2-tolylpropane (4), and 1,3-bis(2-pyridyl)-2-ferrocenylpropane (5) as chelate ligands (L-L) have been synthesized. The crystal structures of 1,3-diphenyl-2,4-di-pyridin-2-yl-butan-1-ol (3b), 5, [(2)PdCl2], [(4)PdCl2], and [(5)PdCl2] have been determined and show a square planar geometry at palladium(II). The neutral complexes were tested in the polymerization of norbornene and copolymerization of norbornene with norbornene derivatives. The complex bearing the pentyl group exhibited high reactivity to give up to 5.9 x 10(5) in molecular weight for the homopolymerization. When [(4)PdCl2] or [(5)PdCl2] was used as a catalyst, homopolymers insoluble at 150degreesC in trichlorobenzene were obtained. However, copolymerization of norbornene with norbornene derivatives 8a-d catalyzed by [(4)PdCl2] gave soluble copolymers with molecular weights up to 5.1 x 10(5). (C) 2003 Elsevier B.V.

  2-pyridyl ligands and silver salts is described. When 1,3-bis(2-pyridyl)propane (L1), tris[(2-pyridyl)methyl]methane (L2), and 1,3-bis(2-pyridyl)-2-tolylpropane (L3) are used in combination with silver ions, novel discrete metallocyclic complexes are formed in crystals. Moreover, the self-assembly of 1,3-bis(2-pyridyl)-2-phenylpropane (L4) with silver nitrate yields a coordination polymer. The examination

  描述了由柔性2-吡啶基配体与银盐反应而形成的金属超分子的自组装。当使用1,3-双（2-吡啶基）丙烷（L1），三[（2-吡啶基）甲基]甲烷（L2）和1,3-双（2-吡啶基）-2-甲苯基丙烷（L3）时与银离子结合，可在晶体中形成新颖的离散金属环配合物。此外，1，3-双（2-吡啶基）-2-苯基丙烷（L4）与硝酸银的自组装产生配位聚合物。对其溶液的检查表明，该配位聚合物是通过基于溶液的离散金属环物种形成的。
