α-烯烃基硅烷可用α-烯烃基卥代物在四氢呋喃溶液中制成镁试剂,然后再与适当的烷基(苯基)卥代硅烷作用而得。我们合成多种烷基(苯基)异丁烯基硅烷,并确定其物理常数,这些化合物有热稳定性。用这一方法也合成异丁烯基三乙氧基硅烷,它容易水解而生成聚合物。异丁烯基溴化镁和原硅酸乙酯以2∶1的量反应时,未得到二异丁烯基二乙氧基硅烷;因为溶液加热蒸馏时它就很快聚合。
The α-olefin silanes may be obtained by the reaction of an α-olefinylhalide with a magnesium reagent in tetrahydrofuran and then with an appropriate alkyl (phenyl) silanesilane. We synthesize a variety of alkyl (phenyl) isobutenyl silanes and determine their physical constants. These compounds are thermally stable. Isobutyltriethoxysilane is also synthesized by this method, which is easily hydrolyzed to form a polymer. When isobutenylmagnesium bromide and ethyl orthosilicate were reacted in a 2: 1 ratio, no diisobutylenedimethoxysilane was obtained; as the solution was polymerized very quickly as it was heated to distillation.
