The Solvent Path in Square-Planar Substitutions. Kinetics and Mechanism for Reactions of Tetrachloroplatinate(II) and Aquachloroplatinates(II) with Halides, Thiocyanate and Dimethyl Sulfoxide
The kinetics for the reactions between the six complexes PtCln(H2O)4-n−2n, n = 0,1,2,3,4 (including cis- and trans-isomers for n=2) and the entering ligands Y = Cl−, Br−, I−, SCN−, and DMSO have been studied. The experiments with PtCl42− and trans- PtCl2(H2O)2 give the usual two-term rate constant kexp = k1 + k2[Y], when no extra chloride has been added to the solutions. The parameter k1 can be id
