Oligosiloxane mit funktionellen Gruppen. II Reaktion von 1,4-Bis(trimethylsiloxy)-but-2-en mit H-Silanen in Gegenwart von Hexachloroplatin-säure

Oligosiloxanes with Functional Groups. II. Reaction of 1.4-Bis(trimethylsiloxy)-but-2-ene with H-Silanes in the Presence of Hexachloroplatinic Acid The synthesis of silicon-modified butane-1.4-diol derivatives by the hydrosilylation of 1.4-bis (trimethylsiloxy) but-2-ene (1) is described. Under the conditions of the hydrosilylation 1 is isomerized with high selectivity. At a temperature above 150°C hydrosilylation and isomerization take place simultaneously.
