## Organo-silicon compounds S 0060 Regiochemical Aspects of the Platinum Oxide Catalyzed Hydrosilylation of Alkynes. -It is demonstrated, that heterogeneous PtO 2 is a useful catalyst for the hydrosilylation of internal unsymmetrical arylalkynes. The addition of silane (II) as the optimized reagen
It is shown that the solvent and the temperature used during the coordination step in the preparation of an alumina-supported platinum catalyst have large effects on their observed hydrosilylating properties. These unprecedented observations lead to the preparation of a highly active and reusable ca
