Gold-carbon bonds

The first method has been used with haloaryl,1639-1643 urt/m-nitrophenyl,1644 mesityl,255 or ylidegold(I)1645-1648 complexes, which are sufficiently stable to undergo the oxidative addition without cleavage of the gold-carbon bond, an example can be seen in Equation (11) ... [Pg.991]

The complex [AuCl(CO)] undergoes displacement of carbon monoxide with isonitriles to give [AuCl(CNR)] complexes (162, 163), or with other ligands to give species no longer containing a gold-carbon bond. [Pg.69]

The first compound containing four gold-carbon bonds was claimed (2/7) to have been prepared in 1933, but a reformulation of the obtained... [Pg.72]

As a final example, the reaction of a binuclear gold ylide complex with methyl iodide afforded (48, 56), a formal gold(II) center having three gold-carbon bonds [Eq. (80)]. [Pg.78]

The infrared spectrum of [Au2(/a-I)2Me4] has been measured in solution and in the solid state (243, 244) and gives rise to identical band contours. This was taken to indicate that rotation about the gold-carbon bonds... [Pg.78]

Other gold(III) complexes containing one gold-carbon bond include the isonitrile complexes [AuX3(CNR)] (131) and the trimeric imino compounds [Au3 C(OR)=NR 3X6] (X = Br or I), which have been prepared (155) by oxidative addition of halogen to the gold(I) species. [Pg.88]

A considerable difference in reactivity toward gold-carbon bond cleavage is found for methylgold(I) and -gold(III) compounds. Thus, for the reactions with benzenethiol, which proceed by elimination of methane, the following order of reactivity is obtained 207, 208) ... [Pg.100]

Cycloaurated gold halide complexes are also precursors to metallacyclic compounds with three gold-carbon bonds. The first examples of this type were the... [Pg.246]
