Exploiting a dimeric silver transmetallating reagent to synthesize macrocyclic tetracarbene complexes

Zheng Lu, S. Alan Cramer and David M. Jenkins

The researchers synthesized a dimeric tetradente-NHC silver complex, as shown in the figure below. This metal complex was used as a transmetallation agent to make  monomeric tetradente-NHC metal complexes with platinum, palladium, nickel, chromium, gold, iron, cobalt, rhodium, and ruthenium. These metal complexes were studied with single crystal X-ray diffraction, ESI-MS, and other spectroscopic techniques where applicable.
