Rates and Mechanisms for Halide Anation Reactions of Platinum(IV) Complexes
(1977) In Inorganica Chimica Acta 24(3). p.239-246- Abstract
- The bromide anation of tr-PtCl4BrH2O− has been studied at 25 °C and the chloride anations of tr-PtCl4BrH2O− and PtBr5H2O− at 50 °C. These reactions proceed via halide assisted mechanisms, compatible with the experimental rate laws determined. The bromide anation of tr-PtBr4CIH2O− studied at 50 °C gives PtBr5Cl2− via a bromide assisted path and PtBr62− via an REOA-path. The observed rate law is determined. PtBr5Cl2− reacts subsequently with bromide to form PtBr62− via a rate-determining (bromide assisted or REOA) formation of an intermediate aqua complex according to the mechanism given. The observed rate law at 50 °C is determined. All reactions have been studied in a 0.50 M perchloric acid medium.
