Ongoma, Peter published the artcileThe ¦Ð-acceptor effect in the substitution reactions of tridentate N-donor ligand complexes of platinum(ii): a detailed kinetic and mechanistic study, Formula: C3H8N2S, the publication is Dalton Transactions (2012), 41(35), 10724-10730, database is CAplus and MEDLINE.
The nucleophilic substitution reactions of complexes [Pt{4′-(2”’-CH3-phenyl)-2,2′:6′,2”-terpyridine}Cl]CF3SO3, [CH3PhPtCl], [Pt{4′-(2”’-CH3-phenyl)-6-(3”-isoquinoyl)-2,2’bipyridine}Cl]SbF6, [CH3PhisoqPtCl], [Pt{2-(2′-pyridyl)-1,10-phenanthroline}Cl]Cl, [pyPhenPtCl], and [Pt(terpyridine)Cl]+, [PtCl] with a series of nucleophiles: thiourea (TU), N,N-dimethylthiourea (DMTU), N,N,N,N-tetramethylthiourea (TMTU), I–, Br–, and SCN– were studied in 0.1 M LiCF3SO3 in methanol (in the presence of 10 mM LiCl). The reactivity of the investigated complexes follows the order pyPhenPtCl > PtCl > CH3PhPtCl > CH3PhisoqPtCl. The lability of the chloride ligand is dependent on the strength of ¦Ð-backbonding properties of the spectator ligands around the platinum center. The exptl. data is strongly supported by DFT calculations The dependence of the second-order rate constants on concentration of the nucleophiles as well as the large neg. values reported for the activation entropy (¦¤S?) confirmed an associative mechanism of substitution.
