    摘要:
    The reactions between trans-[Au(CN) 2 X 2 ] - (X = Cl or Br) and Me 2 S have been studied by conventional and high-pressure stopped-flow spectrophotometry in acidic aqueous solution containing 10% (w/w) methanol. The overall stoichiometry Au III ∶Me 2 S is 1∶(1.0 ± 0.1) in agreement with the reaction: trans-[Au(CN) 2 X 2 ] - + Me 2 S + H 2 O → [Au(CN) 2 ] - + Me 2 SO + 2H + + 2X - . Initial rapid substitution processes result in the formation of a pre-equilibrium between transient gold(III) complexes, which are reduced to [Au(CN) 2 ] - in a subsequent slower redox process. Complexes trans-[Au(CN) 2 X(Me 2 S)] with an asymmetric electron distribution along the X–Au–S axis are reduced rapidly via an intermolecular process, in which Me 2 S attacks a co-ordinated halide. The complex trans-[Au(CN) 2 (Me 2 S) 2 ] , on the other hand, undergoes slow reduction to gold(I) involving a water molecule. The rapid halide-mediated oxidation of thioethers implies that reduction of metal ions in biological systems by such moieties should be favoured in extracellular environments, where the chloride concentrations are high.

  • 1H, 13C NMR and UV spectroscopy studies of gold(III)-tetracyanide complex with l-cysteine, glutathione, captopril, l-methionine and dl-seleno-methionine in aqueous solution

    with biologically important thiols, thioether and selenoether were carried out and monitored using 1H, 13C NMR and UV spectroscopy. These ligands include l-cysteine, glutathione, captopril, l-methionine and dl-seleno-methionine. Thiols show very strong affinity to be oxidized into the disulfide by auricyanide, which gets reduced to aurocyanide [Au(CN)2]−. l-cysteine reaction mechanism with [Au(CN)4]−
    使用1 H,13 C NMR和UV光谱法进行并监测了Auricyanide [Au(CN)4 ] -与生物学上重要的硫醇,硫醚和硒醚的相互作用。这些配体包括l-半胱氨酸,谷胱甘肽,卡托普利,l-蛋氨酸和dl-硒代蛋氨酸。硫醇显示出很强的亲和力,可被金硫氰酸盐氧化为二硫键,而被还原为金硫氰酸盐[Au(CN)2 ] -。发现具有[Au(CN)4 ] -的l-半胱氨酸反应机理取决于反应物的摩尔比。虽然L-蛋氨酸对金刚烷胺完全呈惰性,但dl-Se-蛋氨酸与[Au(CN)4 ]具有一定的反应性。−将溶液的pH升高至12以利于氰化物交换之后。

    respectively, corresponding to the two equilibrium components, [CSeAuCN] and [Au(CN) 2 ] − . Equilibrium constants ( K eq ) were determined for the scrambling equilibria by integrating the CN − resonances in the 13 C NMR, recorded at 297 K. K eq values obtained for cyano(selenone)gold(I) complexes are the highest of all the reported values, measured for other complexes.
    摘要制备了许多新的氰基(硒烯酮)金(I)配合物,并通过元素分析,IR和NMR方法对了一系列硒酮(咪唑烷-2-硒酮及其衍生物或重氮烷-2-硒酮)进行了表征。从红外数据看,制备的七个络合物中有两个以非离子络合物形式存在[CSeAuCN],而其余五个以离子形式存在[Au(CSe)2] + [Au (CN)2]-处于固态。在溶液中,观察到所有络合物均发生配体加扰反应,表现出平衡[2 [CSeAuCN]⇆[(CSe)2 Au] + [Au(CN)2]-。配合物的配体加扰反应已在DMSO中使用13 C和15 N NMR光谱进行了研究。加扰反应的结果是,在13 C和15 N NMR中,CN-的碳和氮在所有配合物中均观察到两个尖锐的共振,分别对应于两个平衡成分[CSeAuCN ]和[Au(CN)2]-。通过积分13 C NMR中的CN-共振来确定加扰平衡的平衡常数(K eq

    A series of gold- and silver-containing ionic liquids, [CnMIM][M(CN)2] (M = Au, Ag; n = 12, 14, 18), prepared by metathesis reactions, present luminescence depending on their physical state i.e. crystalline or smectic A phases. The photoluminescent measurements as well as DFT calculations suggest that the modulation of aurophilic intermolecular interactions are responsible for this phosphorescent behaviour.
