[dimethoxy(methyl)silyl]oxy-dimethoxy-methylsilane

反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: A flask was charged with 216 g of γ-methacryloxypropyldimethylmethoxysilane and 500 g of methanol. Under a nitrogen stream, the flask was cooled to 5° C., to which 18.0 g of 0.2N acetic acid was added dropwise over 15 minutes while the liquid temperature was maintained below 10° C. After the completion of dropwise addition, stirring continued for one hour at room temperature. Then, 2260 g of 1,3-dimethyl-1,1,3,3-tetramethoxydisiloxane was added. Stirring continued for 2 hours at room temperature and for a further 8 hours at 60° C. The methanol and volatile matter were removed from the reaction solution by heating in vacuum, obtaining 1-(γ-methacryloxypropyl)-3,5-dimethyl-3,5,5-trimethoxytrisiloxane (M-2) in a yield of 82%. was added dropwise over 15 minutes while the liquid temperature was maintained below 10° C After the completion of dropwise addition Stirring continued for 2 hours at room temperature and for a further 8 hours at 60° C The methanol and volatile matter were removed from the reaction solution by heating in vacuum
