  Vinyl-addition polymerization of norbornene catalyzed by (pyrazol-1-ylmethyl)pyridine divalent iron, cobalt and nickel complexes

  摘要：

  Complexes of 2-((3,5-dimethyl)-1H-pyrazol-1-ylmethyl)pyridine (L1), 2-((3,5-ditert-butyl-1H-pyrazol-1-yl)methyl)pyridine (L2), 2-((3,5-diphenyl)-1H-pyrazol-1-yl)methyl)pyridine (L3), 2-((3,5-bis(trifluoromethyl)-1H-pyrazol-1-ylmethyl)pyridine (L4) and 2,6-bis(3,5-dimethyl-1H-pyrazol-1-y1)methyl) pyridine (L5) with cobalt(II), iron(II) and nickel(II), Ni(L1)Cl-2 (1), Co(L1)Cl-2 (2), Fe(L1)Cl-2 (3), Ni(L2)Cl-2 (4), Ni(L3)Cl-2 (5), Co(L3)Cl-2 (6), Fe(L3)Cl-2 (7), Ni(L4)Cl-2 (8) and Ni(L5)Cl-2 (9), were used as catalyst precursors to produce vinyl-addition type norbornene polymers. Both the identity of the metal center and nature of ligand affected the polymerization behaviour of the resultant catalysts. Nickel catalysts were generally more active than the corresponding iron and cobalt analogues. The polynorbornene produced have high molecular weights (0.5-2.1 x 10(6) g/mol) and narrow molecular weight distributions. Analyses of polymer microstructure using NMR and IR spectroscopy confirmed the polymers produced to be vinyl-addition polynorbornene. (C) 2011 Elsevier Ltd. All rights reserved.

Treatment of complex 1 with equimolar amounts of PPh3 or PPh3/NaBAr4 produced the corresponding cationic complexes [Pd(L1)ClPPh3]Cl (4) and [Pd(L1)ClPPh3]BAr4 (5), respectively.

  The structural and kinetic studies of polymerization reactions of ε-caprolactone (ε-CL) using (pyrazolylmethyl)pyridine Cu(II) and Zn(II) complexes as initiators is described. Reactions of 2-(3,5-dimethylpyrazol-1-ylmethyl)pyridine (L1) and 2-(3,5-diphenylpyrazol-1-ylmethyl)pyridine (L2) with Zn(Ac)2·2H2O or Cu(Ac)2·2H2O produced the corresponding complexes [Zn(Ac)2(L1)] (1), [Cu(Ac)2(L1)] (2), [Zn(Ac)2(L2)]

  Reactions of 2-(3,5-dimethylpyrazol-1-ylmethyl)pyridine (L1), 2-(3,5-diphenylpyrazol-1-ylmethyl)pyridine (L2), 2-(3,5-di-tert-butylpyrazol-1-ylmethyl)pyridine (L3) and 2-(3-p-tolylpyrazol-1-ylmethyl)pyridine (L4) with K-2[PtCl4] in a mixture of ethanol and water formed the dichloro platinum complexes [PtCl2(L1)] (1), [PtCl2(L2)] (2), [PtCl2(L3)] (3) and [PtCl2(L4)] (4). Complex 1, [PtCl2(L1)], could also be prepared in a mixture of acetone and water. Performing the reactions of L2 and L3 in a mixture of acetone and water, however, led to C-H activation of acetone under mild conditions to form the neutral acetonyl complexes [Pt(CH2COCH3) Cl(L2)] (2a) and [Pt(CH2COCH3) Cl(L3)] (3a). The same ligands reacted with HAuCl4 center dot 4H(2)O in a mixture of ethanol and water to form the gold salts [AuCl2(L1)][AuCl4] (5) [AuCl2(L2)][Cl] (6) [AuCl2(L3)][Cl] (7) and [AuCl2(L4)][AuCl4] (8); however, with the pyrazolyl unit in the para position of the pyridinyl ring in 4-(3,5-dimethylpyrazol-1-ylmethyl)pyridine (L5), 4-(3,5-diphenylpyrazol-1-ylmethyl)pyridine (L6) neutral gold complexes [AuCl3(L5)] (9) and [AuCl2(L6)] (10) were formed; signifying the role the position of the pyrazolyl group plays in product formation in the gold reactions. X-ray crystallographic structural determination of L6, 2, 3 3a, 8 and 10 were very important in confirming the structures of these compounds; particularly for 3a and 8 where the presence of the acetonyl group confirmed C-H activation and for 8 where the counter ion is AuCl4-. Cytotoxicity studies of L2, L4 and complexes 1-10 against HeLa cells showed the Au complexes were much less active than the Pt complexes. (C) 2009 Elsevier B. V. All rights reserved.

  The title compound, [PdCl₂(C₂₁H₁₇N₃)], is a member of a sequence of Pd, Pt and Co dichloride complexes bearing polysubstituted (pyrazol-1-ylmethyl)pyridine ligands. It is shown that there is a correlation between the steric bulkiness of the bidentate (pyrazol-1-ylmethyl)pyridine ligands and the Pd—N_pyrazoledistances,i.e.the larger the ligand, the longer the bond. In contrast, no trend is observed between the steric properties of the ligand and the Pd—N_pyridinebond lengths.
