Versuchsvorschrift

Butanol solution of chloroplatinic acid was added to 198 g of vinylmethyldimethoxysilane, and to this mixture, 159 g of dimethoxymethylsilane was gradually added dropwise. Due to the exothermic nature of the reaction, the speed of the dropwise addition was adjusted so that temperature of the reaction mixture was up to 80° C. After the completion of the dropwise addition, the mixture was distilled at reduced pressure under clean conditions as in the case of Synthetic Example 1 to obtain 1,2-bis(dimethoxymethylsilyl)ethane.
