Abstract

The use of (NHC)AgX salts as transmetallating agents for platinum can be tuned to introduce either one or two NHC ligands per platinum in high yield. Complexes with a single NHC ligand are prepared with an additional DMSO ligand, which can conveniently be replaced by other ligands such as phosphines to give mixed cis NHC/phosphine complexes. Variable-temperature NMR and DFT have been used to probe the nature of the restricted rotation of the NHC ligand about the square planar platinum center: experimentally, the barrier has been established as at least 85 kJ mol(-1), and the computational value has been determined to be 92 kJ mol(-1).
