چکیده انگلیسی
The kinetics of displacement by chloride of meta- and para-substituted pyridines (R-py) from [Pt(SNS)(R-py)]2+ complexes {SNSÂ =Â 2,6-bis(methylsulfanylmethyl)pyridine} are reported. The reactivity of the two groups of N-donors is different, the meta-substituted pyridines resulting less reactive than the para-substituted on growing their basicity. These results have been explained on the basis of a different Ï-acidity between the two groups of ligands which influences the reaction ground state.
