Abstract

A process for the addition of Si-bonded hydrogen to an aliphatic multiple bond in the presence of a platinum catalyst selected from the group consisting of ______________________________________ I XPtY, II ##STR1## III APt(Y')X"and ______________________________________ mixtures thereof, in which A is a halogen, X is a substituted or unsubstituted hydrocarbon radical having from 1 to 3 aliphatic double bonds which is bonded to the platinum atom via a PtC-sigma bond and a Pt-olefin-Pi-bond, X' is a hydrocarbon radical which is substituted with an alkoxy or acyloxy group and has from 1 to 3 double bonds and is bonded to the platinum atom via a PtC-sigma bond and a Pt-olefin-Pi-bond, X" is a substituted or unsubstituted hydrocarbon having an aliphatic double bond which is bonded to the platinum atom via a Pt-olefin-Pi-bond, Y is a chelate-like bonded beta-diketonate ligand or arylcarboxylate ligand, Y' is a beta-diketonate ligand and Z is a double link bridge ligand.
