The reactions of various alkoxytrichlorosilanes prepared in situ from tetrachlorosilane and alcohols, with Grignard reagents bearing a bulky substituent such as the isopropyl, sec-butyl, and cyclohexyl group afforded triisopropyl-, tri(sec-butyl)-, and tricyclohexylalkoxysilane in high yields. The reactions of n-butoxytrichlorosilane with these Grignard reagents produced triisopropyl-, tri(sec-butyl)-
由四氯硅烷和醇原位制备的各种烷氧基三氯硅烷与带有大体积取代基的格利雅试剂如异丙基,仲丁基和环己基的反应,可高收率得到三异丙基,三(仲丁基)和三环己基烷氧基硅烷。的反应Ñ -butoxytrichlorosilane与这些格氏试剂制备三异丙基,三(仲丁基,和三环己基( -丁基)ñ分别在94%,96%,和92分%的收率丁氧基)硅烷,。甲氧基甲基二氯用相同的格氏试剂反应,得到二异丙基,二(仲丁基-丁基)-和二环己基甲氧基甲基硅烷,产率分别为84%,83%和83%。用格氏试剂对甲氧基二甲基氯硅烷的处理容易地以优异的产率得到异丙基,仲丁基和环己基甲氧基二甲基硅烷。用叔丁基氯化镁对甲氧基二甲基氯硅烷进行类似处理,以62%的收率得到叔丁基甲氧基二甲基硅烷。
