Abstract

The invention relates to a method for producing trimethylplatinum(IV) iodide and trimethylplatinum(IV) iodide obtainable according to said method and the use thereof as a reactant for producing platinum(IV) compounds, as a precatalyst and as a catalyst. The platinum(IV) compounds thus obtainable, as well as the use thereof as precursors for the deposition of platinum layers and platinum-containing layers on a surface of a substrate are also the subject matter of the invention. The invention also relates to a substrate comprising a platinum layer or a platinum-containing layer on a surface, and to a method for producing an electronic component, in particular an electronic semiconductor component, or an electrode for a fuel cell using a platinum(IV) compound obtainable using trimethylplatinum(IV) iodide, which is obtainable by means of the method described herein.
