Cyclometalated Analogues of Platinum Terpyridine Complexes: Kinetic Study of the Strong -Donor Cis and Trans Effects of Carbon in the Presence of a -Acceptor Ligand Backbone

The substitution kinetics of the complexes [Pt(N-N-C)Cl] (N-N-CH = 6-phenyl-2,2ʹ-bipyridine), [Pt(N-C-N)Cl] (N-CH-N = 1,3-di(2-pyridyl)benzene), and [Pt(N -N-N)Cl]Cl (N-N-N = 2,2ʹ:6ʹ,2ʹ ʹ-terpyridine) with the nucleophiles Br-, I-, and, for the first two complexes, also thiourea, N,N-dimethylthiourea, and N,N,Nʹ,Nʹ-tetramethylthiourea, have been studied in methanol as solvent.
