Ligand substitution reactions gold

In contrast, those cluster compounds with an 18-electron environment at the central heterometal do not undergo nucleophilic addition reactions. Ligand substitution reactions at both the central heterometal and the peripheral gold atoms are observed to occur for both 16- and 18-electron cluster compounds, as in the reactions shown below ...

Another general procedure to prepare gold(II) complexes consists of substitution reactions on gold(II) derivatives. Halide ligands can be substituted by neutral donor ligands2025-2032 such as... [Pg.1021]

Schwarz s group (154, 176) studied substitution reactions of gold complexes (AuL+), where L is a neutral ligand), and discussed the relative Au(I) affinity for ligands. [Pg.384]

Optically active ferrocenylbisphosphines, (/J)-N,iV-dimethyl-l-[(5)-1, 2-bis(diphenylphosphino)ferrocenyIJethylamine [(/J)-(5)-BPPFA] and its derivatives, are efficient chiral bisphos-phine ligands for rhodium-catalyzed asymmetric hydrogenation, palladium-catalyzed asymmetric allylic substitution reactions, and gold-catalyzed asymmetric aldol-type reactions of a-isocyano carboxylates. ...
