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。

A aeries of alkyl (phenyl) iso-butenylsilanes have been prepared by the reaction of iso-butenyl-magnesium bromide with different alkyl (phenyl) chlorosilanes in tetrahydrofuran and their physical constants were determined. With the same .method, we have prepared iso-butenyl triethogysilane. The latter was easily hydrolyzed and polymerized. When iso-butenylmagnesiurn bromide and tetraethozysilane were mixed in proportion of 2:1, no diiso-butenyl diethoxy-ailane was obtained.
