Procedure

A mixture containing 296 g of tris-(trimethylsiloxy)silane, 110 g of allyl acetate and 2.4 g of ruthenium supported on activated charcoal (5 percent by weight of ruthenium and 95 percent by weight of activated charcoal), in which the 2.4 g refers to the total wieght of the charcoal and the ruthenium, are heated to boiling under reflux (approx. 105° C.) for 4 hours. The tris-(trimethylsiloxy)-acetoxysilane yield is quantitative.
