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 ...

A Nucleophilic Gold(III) Carbene Complex
Angewandte Chemie International Edition, 2017Abstract The first Au III carbene complex was prepared by reacting a geminal dianion with a (P,C) cyclometalated Au III precursor. Its structure and bonding situation have been thoroughly investigated by experimental and computational ...

Gold(III) Complexes in Medicinal Chemistry
Future Medicinal Chemistry, 2014A number of gold(III) compounds has been designed with the objective of overcoming the disadvantages associated with the platinum-based drugs for cancer treatment. Compounds of a remarkable structural manifold show significant antiproliferative effects in vitro against a number of cancer cells, including cisplatin resistant ones.

Pentachlorophenyl Complexes of Gold(I) and Gold(III)
Synthesis and Reactivity in Inorganic and Metal-Organic Chemistry, 1984Abstract 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 ...

Chelate complexes of gold(III)
Hyperfine Interactions, 1988New gold(III) complexes involving substituted picolinic acids acting as bidentate ligands have been characterised: [AuCl2(LL′), and [Au(LL′)2]+ (H-LL′=hydroxy- or carboxy-substituted picolinic acid). The latter readily undergo deprotonation of the substituent on one ligand, to yield novel uncharged complexes which appear to be polymeric via hydrogen ...

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)

Cross-coupling of arene–gold(III) complexes
Tetrahedron, 2013Abstract The reactivity of electron-deficient arene–gold(III) complexes toward nucleophilic aromatic and heteroaromatic counterparts has been studied. 1-Methylindole proved to be the best reaction partner while trimethoxybenzenes did not react. The ancillary ligand on gold also influenced the reactivity in the order PPh3>PtBu3>IPr. An oxidative cross-
