Gold-197 Mössbauer spectra of organogold( I ) compounds

J. Chem. Soc., Dalton Trans., 1983
Gold-197 Mossbauer parameters are reported for the salts Z[AuR2]{R = C6F5, Z =[NBu4]+, [Ag(C4H8S)]+, [Au(SbPh3)4]+, or [Au(pdma)2]+[pdma =o-phenylenebis(dimethylarsine)]; R = C6F3H2, Z =[NBu4]+, Ag+, or [Ag(C4H8S)]+}. For salts of the same cation, the isomer shift and quadrupole splitting are both slightly smaller for R = C6F5 than for R = C6F3H2, in ...

Synthesis and Structural Characterization of Stable Organogold(I) Compounds. Evidence for the Mechanism of Gold-Catalyzed Cyclizations

Journal of the American Chemical Society, 2008
The vast majority of homogeneous Au-catalyzed reactions have exploited the propensity of Au to activate unsaturated carbon-carbon bonds as electrophiles. It is generally assumed that a nucleophile attacks a gold-activated carbon-carbon multiple bond to give an alkenyl Au intermediate, notwithstanding the fact that these intermediates are hitherto ...

The molecular structure of some amorphous organogold compounds studied by the radial distribution function method

Journal of Organometallic Chemistry, 1987
Abstract The method of radial distribution functions (RDF) of atoms obtained from powder X-ray diffraction patterns has been applied to the determination of the molecular structure of a number of polynuclear organogold derivatives in the form of amorphous powders.

Interactions of the organogold(III) compound Aubipyc with the copper chaperone Atox1: a joint mass spectrometry and circular dichroism investigation

BioMetals, 2015
The so called "copper trafficking system" in mammalian cells is primarily devoted to the regulation of copper transport and homeostasis. This system, now well characterized, consists of a few strictly interconnected proteins that assist copper entrance inside cells and then promote metal transfer and delivery to essential copper-dependent cellular ...

DFT Study of the Structural and Electronic Properties of Selected Organogold(III) Compounds with Characteristic Anticancer Activity

Russian Journal of Physical Chemistry A, 2019
The limitless exploration for the discovery of potential drug candidates for cancer treatment has become a worldwide research priority. More importantly is the chemistry of gold(III) compounds, which has recently undergone intense scrutiny due to their outstanding cytotoxic properties as an emerging class of metal complexes.

Mechanistic studies on two dinuclear organogold(iii) compounds showing appreciable antiproliferative properties and a high redox stability

Metallomics, 2011
Two dinuclear oxo-bridged organogold(III) compounds, namely [(N,N,C)(2)Au(2)(μ-O)][PF(6)](2) (with N,N,CH = 6-(1-methylbenzyl)-2,2'-bipyridine, Au(2)O1; or 6-(1,1-dimethylbenzyl)-2,2'-bipyridine, Au(2)O2), were previously prepared and characterised. Their solution chemistry under physiological-like conditions has been investigated here as well as their
