    摘要： 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.

    摘要： A method for producing a cyanide-free solution of a gold compound that is suitable for gold electrodeposition baths. The method includes the steps of reacting at least one of a cysteine and a cysteinate with at least one of tetrachloroauric acid and a tetrachloroaurate in a first aqueous medium, separating a resulting precipitate from the first aqueous medium, and dissolving the precipitate in a second aqueous medium with elevation of the pH to 12.0-14.0.
