As a platinum catalyst when attaching Si-bonded hydrogen to an aliphatic multiple bond, a solution is used which was prepared byn n n initially dissolved in at least 20 parts by weight of olefin per part by weight of platinum halide from platinum and halogen, optionally platinum halide, in particular platinum tetrachloride, in addition to hydrogen and oxygen, andn n n then the solution thus obtained was heated in a mixture with 0.5 to 1 mol per gram atom of platinum primary and / or secondary amine. |
