Organogold! 11 compounds

There are considerable numbers of the organogold compounds [3(b), 9,154], principally in the +1 and +3 oxidation states. Gold is unusual in transition metals in that, even in the +1 state, it has a marked preference for forming a-rather than zr-bonds, presumably related to the tendency of gold(I) to linear 2-coordination.

Gold(i) alkynyls and their complexes have been an important class of organogold compounds from the very beginning of organogold chemistry.2 By contrast, the class of gold(m) alkynyls is poorly developed and only a small number of representative compounds is known. Alkynylgold compounds have recently been reviewed, focusing on various aspects of their chemistry.40-43... 

Carbenes form stable complexes with many metals in the periodic table of the elements, and gold is no exception. In fact, the chemistry of this class of organogold compounds for some time has been one of the fastest growing subdisciplines. While the corresponding chapters were still short in previous accounts,1 2 the inventory for this review is now particularly rich and diverse.230 As for other classes of carbene complexes, this upsurge is based on expectations for potential applications in various fields such as NLO materials, liquid crystalline phases, and catalysis. Where applicable, this is indicated for each of the entries in this chapter.

Further preliminary studies of direct auration of furane and thiophene derivatives were performed by Schmidbaur et al., who synthesised several organogold compounds similar to 89 or 90 [71] and the research of He and Shi on the gold(III)-catalyzed inter- or intramolecular functionalization of aromatic —H bonds confirmed the possibility of such processes [21] (Figure 8.2). 

The nature of the bonding in organogold compounds has been investigated by X-ray diffraction, as well as by a variety of spectroscopic techniques. Mossbauer and ESCA studies have proved particularly informative in determining the oxidation state of the gold center, and vibrational and NMR spectra have been utilized in assigning molecular geometries. 

A number of comparative studies have been made of organogold compounds and related complexes of neighboring metals, notably platinum and mercury as well as the other group IB elements. These comparisons have included such aspects of their chemistry as thermal stability and reactivity, bonding modes, and spectroscopic data.
