Ten grams of the potassium salt of bromoauric acid (KBrA4) are dissolved in 100 cc of 96% ethyl alcohol. This salt is also designated as potassium auribromide. Sulfur dioxide (SO2) is then led through this solution, through a fine capillary tube, for several minutes. This reaction produces aurous bromide (AuBr). The solution of the aurous bromide is then allowed to... [Pg.113]

Molecular weight determinations by cryoscopy in benzene revealed that the MLi2BrAr2 stoichiometry found in the solid state is retained in solution. On the basis of NMR and cryoscopy, it can be concluded that the structural features of the bromoaurate are similar to those of the bromocuprate and -argentate. A multinuclear NMR study shows that the bonding between the [Li-Br-Li] and [Ar-M-Ar] is intermediate between ionic and covalent, with a more covalent Au-C,pjo bond than the Cu-C o or Ag-Cipso ones. A similar trend has also been reported previously by van Koten for tetranuclear compounds of the type [M2Li2 2-CH2NMe2C6H4 4] (M = Cu, Ag, Au).125... [Pg.109]

In most cases, perchlorates are used for the characterization of enamines because of good crystallization properties and the small nucleophilicity of the perchlorate ion. Hexachlorostannates,25 hexachloroantimonates,25 chloroaurates, and bromoaurates have been used occasionally, together with chlorides and bromides, if they are crystalline. [Pg.183]

There is evidence that achieves a co-ordination number of six in complexes. The bromoaurate ion, AuBr4", reacts with bromide ion in nitrobenzene and nitromethane to give the AuBr ", AuBr5 and AugBrjo " ions. [Pg.523]
