Abstract

A process for producing platinum alkenyl polysiloxane complex compounds, especially platinum divinyltetramethyldisiloxane, by reacting a haloplatinum compound with at least one alkenyl polysiloxane in the initial presence of platinum in the form of a platinum complex compound as an autocatalyst and in the initial presence of at least one base in an organic solvent or mixture of organic solvents that can be oxidized by the haloplatinum compound.
