Ag(I) N-Heterocyclic Carbene Complexes: Synthesis, Structure, and Application

“…This deprotonation can lead to decomposition, particularly in ligands where methylene groups are R to the nitrogen atoms on the N-heterocyclic carbene. 27,30,31,37,45,46,79 Scheme 1b,c demonstrates the relative instability of the methylene-linked ligands vs the direct linkages. In Scheme 1b, the pyridine-linked imidazolium salt is deprotonated to produce the free carbene 9, which has been complexed to various metals.…”

Furan- and thiophene-functionalised bis-carbene ligands: Synthesis, silver(I) complexes, and catalysis

“…However, when non-coordinating anions are present the complexes invariably adopt a quasi-linearly dicoordinated Ag(I) cation [2,12,14,15]; bis-NHC ligands typically yield dinuclear [Ag 2 (bis-NHC) 2 ] 2+ complexes [5,[16][17][18], sometimes stabilised by AgÁ Á ÁAg interactions in the solid state [16,18]. Syntheses conducted in the presence of excess Ag 2 O or Ag + may yield products incorporating additional silver ions that participate in metal-metal interactions [15,19].…”

“…Syntheses conducted in the presence of excess Ag 2 O or Ag + may yield products incorporating additional silver ions that participate in metal-metal interactions [15,19]. Notably, Ag(I) has little affinity for additional nucleophilic functional groups when ligated by two NHC ligands so these have little structural influence [5,[15][16][17]20]. This lack of interaction may, at least in part, explain the compatibility of the ÔAg 2 O routeÕ to complexes of functionalised NHC ligands, although it would seem that the tolerance of Ag 2 O towards activated hydrogens adjacent to functional groups is key to its versatility.…”
