1,1-Dimethyl-1-silacyclopentan-3-ols are synthetised by hydroboration—oxidation or epoxidation—reduction of the corresponding silacyclopent-3-enes. In acidic media, β-silacyclopentanols give ring opening reactions. Secondary sila-β-alcohols are rearranged by Raney nickel on warming to give 1-oxa-2-sila-cyclopentanes. Thermal dehydration of tertiary β-alcohols gives a mixture of cyclenic isomers from
通过氢硼化-氧化或环氧化-还原相应的硅杂环戊-3-烯而合成1,1-二甲基-1-硅杂环戊烷-3-醇。在酸性介质中,β-硅环戊醇会发生开环反应。兰尼镍在加热后会重新排列次要的Sila-β-醇,以生成1-oxa-2-sila-环戊烷。叔β-醇的热脱水产生了周期异构体的混合物,可以从中制备α-硅杂环戊醇。
