0.5 ml of a 0.1 N solution of chloroplatinic acid as the catalyst in 2-propanol was added to an excess amount [58.1 g (581 mmol)]of allyl acetate (B). 40 g (15.4 mmol) of triphenylsilane (A) was added thereto and the mixture was stirred at room temperature for 3 h. After confirming the completion of the reaction according to the disappearance of an absorption due to SiH at 2100 cm-1 in the I.R. absorption spectrum, excess (B) was distilled off under reduced pressure. The residue was purified according to column chromatography to obtain 51.1 g (14.2 mmol) of 3-acetoxypropyltriphenylsilane (C) (yield: 92.2%).
