Procedure: A mixture containing 14.8 g of 1,1,1,3,3-pentamethyldisiloxane, 10.0 g of allyl acetate (acetic acid allylester) and 0.01 g of palladium supported on activated charcoal, in which the 0.1 g refers to the total weight of the charcoal and the palladium, is heated to boiling under reflux (approximately 105° C.) for 4 hours. The 1,1,1,3,3-pentamethyl-3-acetoxydisiloxane yield is quantitative.
