实验过程

In the same reactor vessel, the 3-(4-acetoxy-3-methoxyphenyl)propene was heated to 80° C. and then charged with chloroplatinic acid (0.79 grams). Trimethoxysilane (1990 grams, 16.3 moles) was added with stirring to the reaction mixture over a period of 40 minutes. An ice bath was used to maintain the reaction mixture at a temperature of between 100 and 108° C. After the addition of the trimethoxysilane, the reaction mixture was held at 90° C. for 1 hour and then the mixture was cooled to room temperature. The product was distilled under vacuum at 143° C. and 1 mm Hg.
