  Pyridyl- and pyrimidyl-phosphine-substituted [FeFe]-hydrogenase mimics: Synthesis, charaterization and properties

  摘要：

  Two tetranuclear iron-sulphur complexes {[(mu-pdt)Fe-2(CO)(5)](2)(PNP) (2) and [(mu-pdt)Fe-2(CO)(5)](2)(PNNP) (3)} and three dinuclear ones {[(mu-pdt)Fe-2(CO)(5)](PNP) (4), [(mu-pdt)Fe-2(CO)(5)](PNNP) (5) and [(mu-pdt) Fe-2(CO)(5)](PNN) (6)} were synthesized, using two new pyrimidyl-phosphine ligands PNNP [4,6-bis( diphenylphosphino) pyrimidine] and PNN (4-tertiary butyl-6-diphenylphosphino pyrimidine) together with the reported pyridyl-phosphine PNP [bis(diphenylphosphino) pyridine] as substituents to react with Fe-2(mu-pdt)(CO)(6). The molecular structures of 2, 3 and 6 were confirmed by single-crystal X-ray analyses, which show that all phosphine ligands occupy the apical positions, while the space group of 3 (P21/n) is different from that of 2 (P-1). Cyclic voltammograms reveal that pyrimidyl-phosphine substituted complexes 3, 5 and 6 present two reduction waves in CH2Cl2 solutions, while pyridylphosphine substituted 2 and 4 show only one. The DFT computational studies demonstrate that the contributions to the LUMO of 3 are comparable from the two Fe2S2 centres and ligated PNNP ligand, which is different from those of other [Fe2S2] mimics in this work.

• Synthesis of a tetratopic bisphosphine ligand derived from pyrimidine and its incorporation into gold and silver coordination polymers

  Herein we present the synthesis of a tetratopic bisphosphine ligand derived from 4,6-disubstituted pyrimidine scaffold. This new ligand (2) was doubly alkylated using iodomethane to give bisphosphonium dication (3) as an iodide salt, and was also coordinated to both gold(I) chloride to give the metal complex (4) and to silver(I) triflate to give a coordination polymer (5), respectively. All compounds

  在本文中，我们介绍了衍生自 4,6-二取代嘧啶支架的四位双膦配体的合成。这种新的配体 ( 2 ) 使用碘甲烷进行双烷基化，得到双膦双阳离子 ( 3 ) 作为碘化物盐，并且还与氯化金 (I) 配位得到金属络合物 ( 4 ) 和三氟甲磺酸银 (I) 以生成分别给出配位聚合物 ( 5 )。所有化合物都已使用多核 NMR 光谱和单晶 X 射线衍射进行了全面表征。 由于 Au(I)–Au(I) 的嗜热相互作用，还发现金络合物4在λmax = 530 nm 处表现出微弱的发射。此外，我们还证明了双膦配体2可用作四位配体，配位聚合物5的形成证明了这一点，其中观察到膦→银和氮→银相互作用。
