“…Those results were interpreted from the molecular structure analysis, which showed that the cis-chelating bis-NHC ligand adopted C 1 -symmetric coordination mode at the metal center instead of the C 2 -symmetric mode. [144] Iridium(I) and rhodium(I) complexes 149-156 with 2,2 0 -bipiperidine-derived NHC donor ligands have been synthesized and characterized (Scheme 22). [145] Complexes were obtained from the corresponding imidazolium salts via the Ag-mediated transmetalation reactions.…”

The field of asymmetric catalysis is rapidly developing and the chiral ligands play a key role in enantioselective transition‐metal catalysis. The electron‐rich chiral N‐heterocyclic carbenes (NHCs) have established themselves as a popular class of stereodirecting ancillary ligands to catalyze enantioselective organic transformations in more efficient ways. Several novel transition‐metal complexes in combination with tailored ligand design have emerged during last few decades in asymmetric catalysis. The tailor‐made NHCs can easily be accessed due to the modular synthesis of their parent azolium salt precursors. Their donor capability and the molecular shape can easily be tuned by changing substituent at N‐atom or by changing the cyclic backbone framework. This review article aims to describe the recent advances in this rapidly evolving research area of enantioselective catalysis using well‐defined transition‐metal complexes possessing chiral NHC donor ligands.

“…Silver NHC complexes with chiral aryl substituents at the nitrogen atoms have been synthesised, 144 as well as a bis-NHC Ag complex which is bridged by a chiral o-xylenylyl unit. 145 Axially chiral mono-NHC Au complexes with a 1,1 0 -biphenyl scaffold 146 as well as bis-NHC Au complexes with a binaphthyl scaffold 147 were synthesised. The reaction of pyridazine-bridged NHC/pyrazole ligands with Ag precursors gives mono-or dinuclear complexes.…”

This article reviews the literature reported during 2011 on gold and silver coordination and organometallic chemistry, focusing on synthetic applications (catalysis, coupling reactions, transmetallation), photochemical properties, biochemical studies as well as compounds with unique structural features. Gold and silver nanomaterials, self-assembled monolayers on Au surfaces as well as other metallic compounds (alloys) of gold and silver are not included.
