Platinum(ii)N-heterocyclic carbene complexes: coordination and cyclometallation. [PDF]
Dalton Transactions, 2010 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.

Chelating N-heterocyclic carbene-carboranes offer flexible ligand coordination to IrIII, RhIII and RuII: effect of ligand cyclometallation in catalytic transfer hydrogenation. [PDF]
Dalton Transactions, 2016 Imidazolium salts linked by an ethyl tether to closo-dicarbadodecaboranes were reacted with [IrCp*Cl2]2, [RhCp*Cl2]2 or [Ru(p-cymene)Cl2]2 in the presence of Ag2O to prepare complexes of the type [MCp*(NHC)Cl2] (M = Ir, Rh; NHC = N-heterocyclic carbene ...

Despite impressive recent momentum gained in C(sp3)–H activation, achieving high regioselectivity in molecules containing different C–H bonds with similar high energy without abusing tailored substitution remains as one of the biggest challenges. The use

Cyclometallation of trimesitylphosphine
Journal of Organometallic Chemistry, 1988Abstract Synthetic and spectral ( 1 H, 13 C and 31 P NMR) details are presented for the formation of cyclometallated palladium(II) and platinum(II) dimers by reaction of trimesitylphosphine with MCl 2 and MCl 2 Y 2 (M Pd, Pt; Y CH 3 CN, PhCN, 1 2 COD) and for the corresponding halide metathesis products.
