Abstract
Benzimidazolium salts and six anionic gold–NHC complexes (NHC = N,N’-dialkylbenzimidazol-2-ylidene) were prepared and characterized. Novel [Au(NHC)2]AuCl2-type complexes were prepared in good yields from silver–NHC complexes by treatment with [AuCl(PPh3)], following the commonly used silver carbene transfer route. All compounds were characterized using 1H and 13C NMR spectroscopy, elemental analysis, and IR. The gold complexes showed antimicrobial activity against Gram-positive/negative and fungal strains.
