Abstract: The present invention relates to a method for preparing di-organo-dialkoxysilanes, in particular di-organo-dialkoxysilanes wherein one or both of the organic substituents are bulky. The method comprises reacting a tetraalkoxysilane compound with a first Grignard reagent to form a mono-organo-tri-alkoxysilane compound, which is then reacted with a chlorinating agent to form a chlorinated mono-organo-di-alkoxysilane which is then reacted with a second Grignard reagent to form the di-organo-di-alkoxysilane compound.

Abstract translation: 本发明涉及二有机 - 二烷氧基硅烷的制备方法，特别是二有机 - 二烷氧基硅烷，其中一个或两个有机取代基是体积大的。 该方法包括使四烷氧基硅烷化合物与第一格氏试剂反应形成单有机三烷氧基硅烷化合物，然后与氯化剂反应形成氯化的单有机二烷氧基硅烷，然后与第二格 格氏试剂，形成二有机二烷氧基硅烷化合物。
