Synthesis and Characterization of Ag(I) and Pd(II) Complexes with a Pyridine Substituted N-Heterocyclic Carbene Ligand

Abstract

Silver NHC complexes are also very useful precursors for NHC complexes of other metals because silver can be easily replaced by another metal ions when reacted with chloride salts of the metal of concern. The formation of insoluble AgCl(s) drives the transmetallation to completion. Employing this transmetallation strategy, a variety of late tran-sition metal-NHC complexes such as Pd, Au, Rh and Ir have been successfully synthesized.
