Photoinduced Gold(I)–Gold(I) Chemical Bonding in Dicyanoaurate Oligomers

Angewandte Chemie International Edition, 2013
Nicht nur σ*σ, sondern auch σ*π: Elektronenstrukturrechnungen zeigen ein σ*σ- und σ*π-Bindungsmuster für AuI–AuI-Bindungen in angeregten Zuständen und legen zwei konformationsabhängige Relaxationsmechanismen für Gold-Dicyano-Oligomere (n=2–5; siehe Bild) in wässriger Lösung nahe. Eine derartige elektronische Struktur der angeregten Zustände könnte auch

The binding of gold(I) to metallothionein

Journal of Inorganic Biochemistry, 1980
The binding of gold(I) to metallothionein, MT, has been unambiguously established by the reaction of Na2AuTM with purified horse kidney MT. Zinc was displaced more readily than cadmium although the latter could be displaced using large Au/Cd ratios. The metal exchange reactions were complete within 2 hr of mixing.

Gold(I) complexes of azoles

Transition Metal Chemistry, 1994
(Dimethyl sulphide)AuCl reacts with azoles to give adducts [LAuX]2 [L = N-methylimidazole (N-MeIm), N-ethylimidazole (N-EtIm), N-propylimidazole (N-PrIm), 2-methylbenzoxazole (2-MeBO) and 2,5-dimethylbenzoxazole (2,5-diMeBO); X = Cl or Br] which were characterized analytically and spectroscopically, including 1H-n.m.r. I.r.

Interaction of Gold Acetylides with Gold(I) or Silver(I) Cations

Organometallics, 2013
Structures and properties of complexes between (trimethylphosphino)gold acetylides and another (trimethylphosphino)gold cation have been studied in the light of the possible “dual activation” reaction mode in gold catalysis. Silver salts are often used as cocatalysts in gold catalysis; therefore, also mixed complexes of acetylides with ...

Gold(I)–Alkanethiolate Nanotubes

Advanced Materials, 2009
A solution approach to assembling Au(I)-alkanethiolates into nanotube structures at room temperature is presented, in which Au(I) cations and alkanethiolate ligands are coordinated into thin platelet forms that then evolve into an open tubular configuration.

A multipurpose gold(i) precatalyst

Chemical Communications, 2011
[Au(tmbn)(2)](SbF(6)) is the first gold(I) complex supported by two nitrile ligands that is indefinitely stable at room temperature. This is a highly versatile precatalyst that can be used for the preparation of active and robust solid-supported gold(I) catalysts.

Photoinitiated Reactions of Haloperfluorocarbons with Gold(I) Organometallic Complexes: Perfluoroalkyl Gold(I) and Gold(III) Complexes

Chemistry – A European Journal, 2019
AbstractThe study of perfluoroalkyl metal complexes is key to understand and improve metal‐promoted perfluoroalkylation reactions. Herein, we report the synthesis of the first gold complexes with primary or secondary perfluoroalkyl ligands by photoinitiated reactions between AuI organometallic complexes and iodoperfluoroalkanes.

Gold(I) and Gold(0) Complexes of Phosphinine-Based Macrocycles

Angewandte Chemie International Edition, 1999
A "CO-like matrix", showing coordination analogous to that of carbonyl groups, is provided by silacalix[4]phosphinine macrocycles. Reaction with Au(I) leads to the first gold(I) complexes of macrocycles, which can be reduced with sodium or potassium to the paramagnetic gold(0) complexes (an example is shown), as evidenced by cyclic voltammetry and EPR ...

Pentabromophenyl Derivatives of Gold(I) and Gold(III)

Synthesis and Reactivity in Inorganic and Metal-Organic Chemistry, 1975
Abstract The preparation of (C6Br5)AuPPh3 and that of the complexes X2Au (C6Br5)PPh3 (X = Cl, Br, I), which were obtained by the reaction of the first with halogens, is described. cis-(C6F5)2Au(C6Br5)PPh 3 was prepared by starting from cis-Cl2 Au(C6Br5)PPh3. All the complexes are stable at room temperature.

Pentachlorophenyl Complexes of Gold(I) and Gold(III)

Synthesis and Reactivity in Inorganic and Metal-Organic Chemistry, 1984
Abstract Au(C6Cls)tht (tht= tetrahydrothiophen), obtained by arylation of AuCl(tht) with LiC6Cl5, reacts with a) neutral ligands to give complexes of the types Au(C6Cl5)L (L= AsPh3 or phen), [Au(C6Cl5)]2dppm or [Au(SbPh3)4]-[Au(C6Cl5)2); b) anionic ligands to give (N(PPh3)2]-[Au(C6Cl5)X] (X= C1 or SCN) and c) chlorine to give tran-Au(C6Cl5)C12(tht ...
