Platinum(II) N-heterocyclic carbene complexes: coordination and Cyclometallation / Petretto, G.L., Miao, W., Jonathan P., R., Zucca, A.. - In: DALTON TRANSACTIONS. - ISSN 1477-9226. - 39:33(2010), pp. 8.7822-8.7825. [10.1039/c0dt00435a]
abstract:
Four different NHC ligands have been coordinated to Pt(II) centres; for the first time cyclometallation
of the NHC ligand was observed, but only when the platinum centre had a DMSO and two methyl
co-ligands. Cyclometallation resulted in the exclusive formation of five-membered rings, and the
absence of any double cyclometallation reactions with appropriate ligands rules out the possibility of
an oxidative addition type mechanism for the cyclometallation reaction.
