	Title	Homogeneous Catalytic Hydrogenation of Unsaturated Compounds with H2PtCl6 + SnCl2 * 2 H20 in iso-Propanol
	Abstract	A catalytical system for homogeneous hy-drogenation of unsaturated compounds, oper-ating under mild conditions can be prepared with H2PtCl6-SnCl2 • 2 H20 and the additives HBr and H20 in m>-propanol. Reaction rates up to 32 mMol • 1 _1 • min -1 were observed. After hydrogenation of one batch new sub-strate can be injected several times without noticeable desactivation of the system. Hy-drogenation rate of 2-tr-cis-hexene is only 0,5 times less than of 1-hexene. Mesityloxide is selectively hydrogenated regarding the double bond.

	Title	Homogeneous and Heterogeneous Catalytic Hydrogenation of Unsaturated Compounds with H2PtCl6 + SnCl2 * 2 H20 in Acetic Acid
	Abstract	The hydrogenation catalyst, prepared by dissolving H2PtCl6 + SnCl2 • 2 H20 in acetic acid operates as a homogeneous or heteroge-neous catalyst, depending on the ratio v = Sn/Pt. Styrene is hydrogenated by the homo-geneous and heterogeneous system but cyclo-hexene only by the heterogeneous system.

	Title	Vergleich der Hydrierung ungesättigter Verbindungen mit einem homogenen und heterogenen Platin-Katalysator in Essigsäure Comparison of Hydrogenation of Unsaturated Compounds with a Homogeneous and Heterogeneous Platinum Catalyst in Acetic Acid
	Abstract	Catalytical hydrogenation of unsaturated compounds in acetic acid with the homo-geneous catalyst prepared from H2PtCl6 + SnCl2 • 2 H20 and the heterogeneous catalyst, prepared from H2PtCl6 and H2, were carried out. A comparison of the results reveals two types of substrates, some are readily hydrogenated by the homogeneous the other ones by the heterogeneous system. Turnover numbers up to 1500 were observed. With the heterogeneous catalyst ethylbenzene is hydrogenated to ethylcyclohexane under mild conditions.
