N-Phosphine oxide-substituted imidazolylidenes (POxIms) have been employed as heteroditopic ligands towards gold centres. Both bis-carbene and mono-carbene gold(i) complexes have been obtained, depending on the steric bulk of the employed POxIm ligand. Ox

, p. 3407 - 3411 (2018)
A digold(I) complex with a pyrene-di-N-heterocyclic carbene ligand has been obtained and fully characterized. The host-guest properties of the complex were studied in chloroform with a series of polycylic aromatic hydrocarbons (PAHs), and the association
Strongly Coordinating Ligands to Form Weakly Coordinating Yet Functional Organometallic Anions
Fisher, Steven P.,McArthur, Scott G.,Tej, Varun,Lee, Sarah E.,Chan, Allen L.,Banda, Isaac,Gregory, Aaron,Berkley, Kevin,Tsay, Charlene,Rheingold, Arnold L.,Guisado-Barrios, Gregorio,Lavallo, Vincent

Weakly coordinating anions (WCAs) are generally tailored to act as spectators with little or no function. Here we describe the implementation of strongly coordinating dianionic carboranyl N-heterocyclic carbenes (NHCs) to create organometallic -ate comple
Catalytic Arylative Endo Cyclization of Gold Acetylides: Access to 3,4-Diphenyl Isoquinoline, 2,3-Diphenyl Indole, and Mesoionic Normal NHC–Gold Complex

, p. 212 - 217 (2021)
3,4-Diphenyl isoquinoline and 2,3-diphenyl indole are readily accessed by catalytic selective bis-arylative endo cyclization of gold acetylides. The synthetic approach could be also extended to prepare six-membered mesoionic NHC complex, which could furth

The synthesis and properties of a series of strongly electron-donating, sterically demanding dialkyl(1,3-diarylimidazolin-2-ylidenamino)phosphines (IAPs) are reported. Determination of the TEP values shows that the bulky IAPs are better donor ligands than
Gold(I) complexes bearing ring-fused benzoxazine-derived triazolylidenes and their use in C–N bond-forming processes

We report the synthesis and full characterization of a novel series of ring-fused benzoxazine-derived triazolium salts (1a–c) and their corresponding triazolylidene gold(I) complexes (2a–c). All new compounds were fully characterized by means of 1H and 13C NMR spectroscopy, elemental analyses, and mass spectroscopy and in the case of triazoliums 1a and 1b by single-crystal X-ray diffraction. The new triazolylidene gold complexes (2a–c) were tested as precatalysts in the hydroamination and hydrohydrazination of terminal alkynes employing aniline derivatives and hydrazine as nitrogen sources, respectively.

A series of mono- to trinuclear gold(I) complexes (1–3) supported by oxo-functionalized 1,2,3-triazolylidenes have been prepared. All new compounds were fully characterized by means of 1H and 13C NMR spectroscopy, elemental analyses, and in the case of complexes 1 and 2 by x-ray diffraction. The catalytic performance of the new triazolylidene gold complexes was tested in several hydroelementation and cyclization processes employing a variety of alkynes as starting materials. According to the overall results, the trinuclear complex 3 displayed the highest catalytic activity in all processes, providing good to excellent yields under mild reaction conditions.
