“…[47] The ligand motif was further used-with different anions or N-substituents (Mes, Ph, iPr, Et, Me, H)-as monodentate or pincer-type ligand for several complexes with palladium, nickel, iridium, and ruthenium, in which the carbene was either prepared first or generated by deprotonation in the presence of a metal precursor. [38,[48][49][50][51][52][53][54][55][56][57][58][59][60][61][62] In 2006, Hahn and Lee et al successfully used silver complexes of phosphine-functionalised benzimidazolin-2-ylidenes as transmetallating agents for the preparation of palladium and platinum compounds. [37,63,64] According to X-ray crystallographic data [64] it seems reasonable that the reaction of phosphine-fuctionalised imidazolium salts with silver oxide leads to different silver species, including those with silver ions coordinating to phosphines.…”
