New structural motifs of silver and gold complexes of pyridine-functionalized benzimidazolylidene ligands

Trinuclear copper(I) complex of 1,3-bis(2-pyridinylmethyl)imidazolylidene as a carbene-transfer reagent for the preparation of catalytically active nickel(II) and palladium(II) complexes

“…The imidazolium salts, 1,3-bis(pyridin-2-ylmethyl)imidazolium hexafluorophosphate ([HL1](PF 6 )) and 1,3-bis(pyridin-2-ylmethyl) benzimidazolium hexafluorophosphate ([HL2](PF 6 )) were prepared according to the known procedures [43,44] Carbene-transfer reaction using a silvereNHC complex as the carbene source has been widely employed for the preparation of transition metal NHC complexes [1]. The gold(I) and Cu(I)eNHC complexes have been scarcely used.…”

“…[HL1](PF 6 ) and [HL2](PF 6 ) were prepared according to the known procedures [43,44]. Ni(PPh 3 ) 2 Cl 2 was synthesized according to the reported methods [61].…”

N‐Phenyl‐substituted carbene precursors and their silver complexes: synthesis, characterization and antimicrobial activities

“…[11] NHCs are most frequently prepared via deprotonation of the corresponding azolium salts such as benzimidazolium, tetrazolium, triazolium and imidazolium, and have been extensively used as organocatalysts and ancillary ligands in transition metal-catalysed reactions. [18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33] Recently, NHC-silver complexes have attracted particular interest because of their wide use as ligand transfer agents to group 8-10 metals, catalysis, nanomaterials and for their different biological activity as antimitochondrial, antimicrobial and anticancer agents.

Synthesis and characterization of 1-phenyl-3-alkylbenzimidazol-2-ylidene salts and their catalytic activities in the Heck and Suzuki cross-coupling reactions

“…N-Heterocyclic carbene (NHC) complexes have high catalytic activities for many organic transformations such as C-C and C-N cross-coupling reactions, C-H bond activation and metathesis [1][2][3][4][5][6][7]. Carbon-carbon cross-coupling reactions have played a very important role in organic synthesis [8].…”
