Abstract
Abstract This invention relates to halogen platinum complexes of the formula A.sub.2 PtX.sub.2 and/or C.sub.3 H.sub.6 PtB.sub.2 X.sub.2 and a process for adding Si-bonded hydrogen to an aliphatic multiple bond in the presence of these halogen platinum complexes, in which A represents the same or different pyridine rings, which are substituted by one or two alkyl radicals having from 1 to 3 carbon atoms, B represents the same or different, 5- or 6-membered heterocyclics or linked 5- or 6-membered heterocyclics having 1 to 2 heteroatoms and X represents the same or different halogen atoms.
