Fluoride complexes of Pt(II) as nucleophiles: activity of PtCl/sub 4//sup 2 -/, PtCl/sub 3/(H/sub 2/O)/sup -/, and PtCl/sub 3/(C/sub 2/H/sub 4/)/sup -/ anions in the oxidative addition of methyl iodide
The kinetics of the oxidative addition of CH/sub 3/I to platinum(II) complexes in aqueous solutions of K/sub 2/PtCl/sub 4/ and KPtCl/sub 3/(C/sub 2/H/sub 4/) have been studied by PMR and GLC. The second-order rate constants for the PtCl/sub 3/(H/sub 2/O)/sup -/ and PtCl/sub 4//sup 2 -/ particles are equal to 400 exp(-2.7 x 10/sup 3//T) and 3.18 x 10/sup 10/ exp(-9.2 x 10/sup 3//T) mole/sup -1/ x liter x sec/sup -1/, respectively. The introduction of a ..pi..-acceptor ligand, viz. ethylene, into the coordination sphere of platinum(II) results in a sharp drop in the rate, probably due to a decrease in the electron density on the platinum atom. According to the PMR data, the product of the oxidative addition of CH/sub 3/I to Zeise's salt is a methyl complex of platinum(IV), is identical to the complex obtained by reacting methyl iodide with K/sub 2/PtCL/sub 4/, and does not contain an olefin.
