Dual facet of gold(iii) in the reactions of gold(iii) and porphyrins
Dalton Transactions, 2012We have firstly demonstrated the dual facet of gold(III) in the reaction between gold(III) and porphyrins, which could be tuned through changing the counter ions, ligands and the electronic effect of the substituents of the porphyrins.

Gold(I) and Gold(III) Trifluoromethyl Derivatives
Chemistry – A European Journal, 2013AbstractTrifluoromethylation of AuCl3 by using the Me3SiCF3/CsF system in THF and in the presence of [PPh4]Br proceeds with partial reduction, yielding a mixture of [PPh4][AuI(CF3)2] (1′) and [PPh4][AuIII(CF3)4] (2′) that can be adequately separated. An efficient method for the high‐yield synthesis of 1′ is also described.

Amine−Amide Equilibrium in Gold(III) Complexes and a Gold(III)−Gold(I) Aurophilic Bond
Inorganic Chemistry, 2007The ligands HN(CH2-2-C5H4N)2, BPMA, and PhCH2N(CH2-2-C5H4N)2, BBPMA, react with Na[AuCl4] to give the cationic complexes [AuCl(BPMA-H)]+ and [AuCl(BBPMA)]2+, respectively. The amido complex [AuCl(BPMA-H)]+ undergoes easy inversion at the amido nitrogen atom and can be reversibly protonated by triflic acid to give [AuCl(BPMA)]2+. The complex [AuCl(BBPMA)

Zeise's salt gets company: 185 years after the report of the well-known platinum(II) ethylene compound, examples of isolable olefin complexes of its isoelectronic neighbor in the periodic table, gold(III), have been prepared (see picture). The complexes are very susceptible towards nucleophilic attack; there is also structural evidence for AuIII–Ag ...

Luminescent (N^C^C) Gold(III) Complexes: Stabilized Gold(III) Fluorides
Angewandte Chemie International Edition, 2015AbstractWe report the design, synthesis, and application of a (N^C^C)‐ligand framework able to stabilize highly electron‐deprived gold(III) species. This novel platform enabled the preparation of C(sp2)‐gold(III) fluorides for the first time in monomeric, easy‐to‐handle, bench‐stable form by a Cl/F ligand‐exchange reaction.

Pentabromophenyl Derivatives of Gold(I) and Gold(III)
Synthesis and Reactivity in Inorganic and Metal-Organic Chemistry, 1975Abstract 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.

Theoretical chemistry of gold. II
Inorganica Chimica Acta, 2005Gold is an element whose unique properties are strongly influenced by relativistic effects. A large body of appropriate calculations now exists and its main conclusions are summarized in this critical review. The present paper completes the recent reviews by Pyykkö (2004, 2005) (529 references).

Reductive carbonylation of gold(III) chloride
Journal of the Chemical Society, Dalton Transactions, 1976The reaction of anhydrous AuCl3 with CO in thionyl chloride gives [Au(CO)Cl] in substantially quantitative yields. The reaction takes place via the intermediate formation of a soluble carbonyl species which has been characterised spectroscopically and is believed to be a mixed-valence carbonyl complex of formula [Au2(CO)Cl4].
