HCID 84824(3,3-Diethoxypropyl)triethoxysilane

Procedure

A round-bottomed flask is introduced with 2 g (1.1 equivalent) of 3,3-diethoxy-1-propene produced in Example 1, and 2 ml (1 equivalent) of triethoxysilane commercially available from Aldrich, Co. Then, hydrogen hexachloroplatinate (H2PtCl6), a metal catalyst, is added in the amount of 1 ppm to the solution. After that, the resulting mixture is allowed to react at 100° C. under atmospheric pressure for 48 hours. Next, the resulting material is fractionally distilled under a vacuum, thereby giving 4.2 g of colorless 3,3-diethoxyprophyltriethoxysilane. The product is dissolved in CDCl3 and measured for 1NMR and infrared-absorbing spectrum. Results are shown in FIGS. 1 and 2.
