摘要：

The kinetics of the substitution reactions between the complexes cis-[Pt(C6F5)2L2] (L = Me2SO, EtS or tetrahydrothiophene) and 2,2'-bipyridine (bipy) to give [Pt(C6F5)2(bipy)] in toluene has been investigated. The results indicate that for the bis(sulfoxide) complex the reaction proceeds via a dissociative mechanism in which there is an initial dissociation of Me2SO to form a three-co-ordinate intermediate, while an associative mechanism is operative for the bis(thioether) complexes. The role of electron density at the platinum atom and of ancillary ligands in determining the reaction pathway is discussed.
