Method for the production of tetrakis(trihydrocarbylphosphane)palladium(0) in organic solvent, whereby 50 to 100% by weight of the organic solvent consist of at least one polar-aprotic solvent, characterised in that a) at least one palladium compound selected from the group consisting of palladium(II) compounds and palladium(IV) compounds that are soluble in the organic solvent is reacted with b) at least one base, selected from the group consisting of alkali metal hydroxides, alkali metal carbonates, alkali metal hydrogen carbonates, alkali metal-C-C-alcoholates, ammonium carbonate, ammonium hydrogen carbonate, alkaline earth metal hydroxides, alkaline earth metal carbonates, alkaline earth metal hydrogen carbonates, alkaline earth metal-C-C-alcoholates, and alkylamines with a total of 2 to 12 carbon atoms; c) at least one trihydrocarbylphosphane; and d) at least one organic reducing agent that is different from the remaining components that are used in the method.

Method for producing tetrakis (trihydrocarbyl phosphane) palladium(0)

Composition for use as catalyst in hydrosilylations, comprising at least one platinum compound selected from the group consisting of Pt[(MeSiCH&#x2550;CH)O]and Pt[(MeSiCH&#x2550;CH)O]and at least one rhodium compound selected from the group consisting of Rh(acac)(CO), Rh(CO)Cl, [Rh(cod)Cl], Rh(acac)(cod), RhH(CO)(PPh), Rh(CO)(PPh)(acac), RhCl(CO)(PPh), and Rh-2-ethylhexanoate at a molar ratio of Pt/Rh in the range of 0.1 to 100.
