  Electrochemical behaviour of cyclometallated gold(III) complexes. Evidence of transcyclometallation in the fate of electroreduced species

  摘要：

  The electrochemical behaviour of a series of neutral and cationic N-C and N-N-C cyclometallated gold(III) species: ([Au(py(1))(Cl)(2)], Hpy(1) = 2-benzylpyridine; [Au(bipy(n))(Cl)][PF6], Hbipy(1) = 6-benzyl-2,2'-bipyridine, Hbipy(2) = 6-(1-methylbenzyl)-2,2'-bipyridine, Hbipy(3) = 6-(1,1-dimethylbenzyl)-2,2'-bipyridine, Hbipy(4) = 6-phenyl-2,2'-bipyridine) has been investigated in different solvent systems using cyclic voltammetry and controlled-potential coulometry. All the species considered show, in cyclic voltammetry, an irreversible one-electron reduction in the potential range -0.9/-1.2 V versus Fc(+/0), using a Pt electrode. On the other hand, exhaustive coulometries have shown the consumption of a number of Faraday per mole within the range 1-2. The very complex decomposition of the electrogenerated species affords elemental gold and significant amounts of different gold by-products. In some situations (e.g. reduction of [Au(bipy(4))(Cl)][PF6]), working with 0.1 mol dm(-3) Na[PF6], CH3C solvent system, it has been possible to characterise the most abundant gold(III) compound, by NMR, FAB-MS, and elemental analysis. The analytical and spectroscopic data provide evidence for the N-C bis-cyclometallated gold(III) derivative (e.g. [Au(bipy(4))(2)][PF6]); the result entails quite an unusual transcyclometallation process. The same compound can also be obtained, albeit in very minor yield, by chemical reduction of [Au(bipy(4))(Cl)][PF6]. (C) 2001 Elsevier Science B.V. All rights reserved.

  Synthesis and characterization of gold(III) adducts and cyclometallated derivatives with 6-benzyl- and 6-alkyl-2,2′-bipyridines

  摘要：

  The reaction of a series of 6-substituted-2,2'-bipyridines HL (N(2)C(10)H(7)R, R = CH(2)Ph, CHMePh, CMe(2)Ph, CH(2)Me, CMe(3) or CH(2)CMe(3)) with HAuCl4 or Na[AuCl4] has been investigated. Under different experimental conditions, salts [H(2)L][AuCl4], adducts [Au(HL)Cl-3] or cyclometallated derivatives [Au(L)Cl][X] (X = AuCl4, BF4 or PF6) have been isolated. The cyclometallated species arise from direct activation of a C-H bond either of a phenyl or a methyl substituent. The structures of an adduct [Au{N2C10H7(CHMePh)-6}Cl-3] and two metallated species [Au{N2C10H7(CMe(2)C(6)H(4))-6}Cl][AuCl4] and [Au{N2C10H7(CMe(2)CH(2))-6}Cl][BF4] . 0.5H(2)O have been determined by X-ray diffraction. In the adduct the gold atom is bonded to the nitrogen atom of the unsubstituted pyridine ring: a long-range interaction with the other nitrogen atom is observed, Au ... N 2.758(4) Angstrom. In the two cyclometallated species the bipyridines act as tridentate N,N,C anions, giving a [5,6] and a [5,5]-fused ring system, respectively. In [Au{N2C10H7(CMe(2)C(6)H4)-6}Cl](+) the hexaatomic N,C ring adopts a boat-like conformation: the structure reveals a rather short interaction between one hydrogen of the Me group in axial position and the gold atom, Au ... H2.62 Angstrom. The pentaatomic N,C ring in [Au{N2C10H7(CMe(2)CH(2))-6}Cl](+) is not planar: the co-ordination around the gold atom is essentially square planar. The new cyclometallated complexes [Au(N,N,C)Cl](+) are compared with those derived from similarly substituted pyridines described previously.

  Replacement of the chloride ligand in the cyclometallated complexes [Au(C,N,N)Cl][PF6] (C,N,N = N2C10H7(CH2C6H4)-6 1, N2C10H7(CHMeC6H4)-6 2, or N2C10H7(CMe2C6H4)-6 3, where N2C10H8 = 2,2′-bipy) by C, N, O and S donor anionic ligands Y was accomplished through different routes depending both on the nature of HY or the C,N,N ligand. Stable alkoxo [Au(C,N,N)(OR)][PF6] (R = Me or Et) and amido [Au(C,N,N)(NHAr)][PF6] (Ar = C6H4NO2-4) complexes were obtained in fairly good yields. The molecular structure of the thiolato complex [AuN2C10H7(CMe2C6H4)-6}(SPh)][PF6] has been determined by X-ray crystallography. The diorganogold(III) complex [Au(C,N,N)(C2Ph)][PF6] on addition of PPh3 (1∶2) undergoes reductive elimination to give [Au(PPh3)2][PF6] and an unsymmetric diarylacetylene.

  在环金属化复合物[Au(C,N,N)Cl][PF6]中，氯配体的替换通过不同的途径完成，具体取决于HY或C,N,N配体的性质，其中C,N,N = N2C10H7(CH2C6H4)-6 1、N2C10H7(CHMeC6H4)-6 2或N2C10H7(CMe2C6H4)-6 3，N2C10H8 = 2,2′-联吡啶。通过引入C、N、O和S供体阴离子配体Y，成功合成了稳定的烷氧基[Au(C,N,N)(OR)][PF6]（R = Me或Et）和酰胺[Au(C,N,N)(NHAr)][PF6]（Ar = C6H4NO2-4）配合物，产率相当不错。通过X射线晶体学确定了硫醇盐配合物[AuN2C10H7(CMe2C6H4)-6}(SPh)][PF6]的分子结构。在添加PPh3（1∶2）后，二烯基金(III)复合物[Au(C,N,N)(C2Ph)][PF6]经历还原消除，生成[Au(PPh3)2][PF6]和一种不对称的二芳基乙炔。
