The electron rich aurate [Au(C6F5)2] also reacts with thallium salts in the presence of a ligand to give extended unsupported gold-thallium linear chain derivatives. The first example... 

Salts with di(alkynyl)aurate(i) anions are very common reagents for the preparation of other gold(i) complexes. A large number of examples with R taken from all sorts of organic functionalities have been prepared and characterized, mainly in a search for new classes with potentially useful photophysical properties (below). 

Anionic alkoxy Fischer-type carbene complexes were shown to react with (Ph3P)AuGl to give a unique vinyl ether complex, which is bound in a quasi-771 fashion to the Cr/Mo centers. Upon treatment with triphenylphosphine, the gold-vinyl ether ligand can be liberated and isolated. This reaction thus gives access for the first time to aurated vinyl ethers (Scheme 57).38... 

Bis[Ar,Ar -di(2-pyridyl)- and -di(2-pyridyl-methyl)-imidazol-2-ylidene]aurate(i) tetrafluoroborates have been prepared from the analogous silver complexes on reaction with (tht)AuCl and their structures determined. The configuration of the cations with sterically well-protected two-coordinate gold centers shows no anomalies. However, fascinating structures are found for the adducts with silver tetrafluoroborate obtained as acetonitrile... 

Di(A, A-dimethyl- and -diethyl-benzimidazol-2-ylidene)gold(i) hexafluorophosphates are photoluminescent in the crystalline state. Metathesis produces an equally luminescent bis(l,2-dicyano-ethene-l,2-ditholato)aurate(m).272... 

Gold catalysts are employed in the arylation of aryl-substituted terminal alkynes (Scheme 18).73 Two different mechanisms are postulated. The first step can be the auration of the arene by gold(m) chloride, generating an arylgold... 

It is suggested that substances such as potassium cliloraurate are dissociated first by ammonia into simple halides, for the alkali clilor-aurates and bromaurates behave towards ammonia like the auric salts.2 Auric bromide, obtained by dissolving precipitated gold in bromine, also absorbs ammonia, the amount depending on the temperature. 

Bis-(3,5-di-tert-butyl-l,2,4-triphospholyl)-bis(triethylphosphine)-digold(I) [36] contains an anionic phosphorus donor ligand. In the crystal structure the cation [bis-(triethylphosphine)gold(I)]+andthe anion[bis(3,5-tert-butyl-l,2,4-triphospholyl) aurate(I)]- associate in pairs through gold-gold interactions.
