|
两篇文献摘要中提及的三氟甲基金属配合物，我不知道这两类配合物有什么用处，请教用途，用在哪些领域，有什么功效，这两篇都是西班牙的那几个整的，便于写论文综述，谢谢。 1：Synthesis and characterization of cobalt complexes of heterocyclic bidentate ligands (N,X), X = S, Se. Valenzuela, E.; Sousa-Pedrares, A.; Duran-Carril, M. L.; Garcia-Vazquez, J. A.; Romero, J.; Sousa, A. Departamento de Quimica Inorganica, Universidad de Santiago de Compostela, Santiago de Compostela, Spain. Zeitschrift fuer Anorganische und Allgemeine Chemie (2007), 633(11-12), 1853-1859. Publisher: Wiley-VCH Verlag GmbH & Co. KGaA, CODEN: ZAACAB ISSN: 0044-2313. Journal written in English. CAN 150:70027 AN 2007:1084966 CAPLUS Abstract The synthesis and structural characterization of homoleptic cobalt pyridine complexes [Co(R-pyX)3] is reported, where X = S, Se; R = H, 3-CF3 and 5-CF3. The compds. were synthesized by electrochem. oxidn. of the metal in a cell contg. an acetonitrile soln. of the corresponding ligand. When 2,2'-bipyridine (bipy) or 1,10-phenanthroline (phen) were added to the electrolytic cell, mixed cobalt(II) compds. [Co(R-pyX)2L] (L = bipy, phen) were also isolated. All of the complexes obtained were characterized by microanal., vibrational and electronic spectroscopy, FAB mass spectrometry and, in the case of diamagnetic compds. that were sufficiently sol., by 1H and 13C NMR spectroscopy. Crystals of [Co(3-CF3-pyS)3] and [Co(5-CF3-pyS)3] were obtained and studied by x-ray diffraction. The crystal structures consist of monomeric mols. with the metal atom in an octahedral environment and the ligands in a meridional disposition. 2：Synthesis and characterization of ruthenium and osmium complexes of heterocyclic bidentate ligands (N,X), X = S, Se. Sousa-Pedrares, Antonio; Duran, Maria Luz; Romero, Jaime; Garcia-Vazquez, Jose Arturo; Monteagudo, Juan C.; Sousa, Antonio; Dilworth, Jonathan R. Departamento de Quimica inorganica, Universidad de Santiago de Compostela, Santiago de Compostela, Spain. Inorganica Chimica Acta (2006), 359(3), 863-876. Publisher: Elsevier B.V., CODEN: ICHAA3 ISSN: 0020-1693. Journal written in English. CAN 144:323554 AN 2006:58880 CAPLUS Abstract The reaction of [RuCl2(PPh3)3] and [OsBr2(PPh3)3] precursors with heterocyclic bidentate (N, X) ligands, X = S, Se, gave [M(R-pyS)2(PPh3)2], (R = H, 3-CF3, 5-CF3, 3-Me3Si); [M(R-pymS)2(PPh3)2], (R = 4-CF3, 4,6-MeCF3) and [M(R-pySe)2(PPh3)2], (R = H, 3-CF3, 5-CF3), where M is Ru or Os, pyS and pymS are the anions of pyridine-2-thione and pyrimidine-2-thione, resp., and pySe is the anion produced by the reductive cleavage of the Se-Se bond in the dipyridyl-2,2'-diselenide. All of the compds. obtained were characterized by microanal., IR, FAB, NMR spectroscopy and by cyclic voltammetry. [Ru(3-CF3-pyS)2(PPh3)2]2(CH2Cl2) (2), [Ru(3-Me3Si-pyS)2(PPh3)2] (4), [Ru(4-CF3-pymS)2(PPh3)2] (5), [Ru(3-CF3-pySe)2(PPh3)2]2(CH2Cl2) (8), [Os(3-CF3-pyS)2(PPh3)2](CHCl3) (11), [Os(3-Me3Si-pyS)2(PPh3)2] (13), [Os(3-CF3-pySe)2(PPh3)2]2(CH2Cl2) (17), [Os(5-CF3-pySe)2(PPh3)2]2(H2O) (18) and [OsCl2(4,6-MeCF3-pymS)(PPh3)2] (19) were also characterized by x-ray diffraction. In all cases, the metal is in a distorted octahedral environment with the heterocyclic ligand acting as a bidentate (N, S) chelate system. |
