Bibliographic Information Versatile method for introduction of bulky substituents to alkoxychlorosilanes. Masaoka, Shin; Banno, Tadashi; Ishikawa, Mitsuo. Hokko Chemical Industry Co., Ltd., Muneage 402, Tamano, Okayama, Japan. Journal of Organometallic Chemistry (2006), 691(1-2), 182-192. Publisher: Elsevier B.V., CODEN: JORCAI ISSN: 0022-328X. Journal written in English. CAN 144:192298 AN 2005:1300600 CAPLUS Abstract Reactions of various alkoxytrichlorosilanes prepd. in situ from tetrachlorosilane and alcs., with Grignard reagents bearing a bulky substituent such as the iso-Pr, sec-Bu, 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)-, and tricyclohexyl(n-butoxy)silane in 94%, 96%, and 92% yields, resp. Methoxymethyldichlorosilane reacted with the same Grignard reagents to give diisopropyl-, di(sec-butyl)-, and dicyclohexylmethoxymethylsilane in 84%, 83%, and 83% yields. Treatment of methoxydimethylchlorosilane with the Grignard reagents readily afforded isopropyl-, sec-butyl-, and cyclohexylmethoxydimethylsilane in excellent yields. Similar treatment of methoxydimethylchlorosilane with tert-butylmagnesium chloride gave tert-butylmethoxydimethylsilane in 62% yield. |
