Mono- and Binuclear Gold(I) Compounds Containing Deprotonated Purines and Pyrimidines

“…These data confirmed that in several cases molecules of solvents can be clathrated in the solids, a frequent observation in the chemistry of the heterocyclic derivatives of gold e.g. : l-(triphenylphosphinegold)-6-methyl-2-pyridone [7] or l-tri(cyc/o-hexyl)phosphinegold-2-/so-propylimidazole [8]. The ligand L is triphenylphosphine for several reasons: the starting compound LAuCl is easily obtained and handled, the corresponding products are generally soluble in organic solvents, and the A u -P bond is not as easily broken as, for example, the A u -As or the A u -Sb bond of similar compounds having triphenylarsine or triphenylstibine in the place of L [8,11].…”

“…Our investigations in the field of gold chemistry have been concerned with the interaction between Au(I) and several nitrogen-containing heterocycles such as pyrazoles [3], pyrazolones [4], indazoles, imidazoles [5], triazoles, tetrazole [6], or pyridones [7]. Isolation and characterization of several N-and of a few C-(trisubstituted phosphine)gold(I) deriva tives of the said molecules was reported.…”

New and Easily Accessible Nitrogen Acyclic Gold(I) Carbenes: Structure and Application in the Gold‐Catalyzed Phenol Synthesis as well as the Hydration of Alkynes

“…[11] Applications of the isonitrile and NAC gold complexes in the field of luminiscent compounds, [12] laser-induced writing with gold on ceramic surfaces, [13] liquid crystals [14] and water-soluble complexes [14] have been reported. The first NHC complex of gold(I) was prepared in 1989, [15] and at present these gold carbene complexes are the dominating car- …”

Novel Benzyl‐ or 4‐Cyanobenzyl‐Substituted N‐Heterocyclic (Bromo)(carbene)silver(I) and (Carbene)(chloro)gold(I) Complexes: Synthesis and Preliminary Cytotoxicity Studies

“…NHCÀGold(I) complexes have been known since 1989, and they can be neutral or cationic, with the respective formulas (NHC)AuX and [(NHC) 2 Au]X [33]. They are now widely used as catalysts for organic transformations such as nucleophilic additions on alkynes [34].…”
