Silylene insertion into allylic ethers occurs suprafacially to provide enantioenriched allylic silanes and disilanes. Silylene insertion to a variety of protected allylic alcohols utilizing silver- and copper-mediated conditions proved to be a general method for allylic silane formation. Allylic disilanes reacted similarly to allylic silanes, undergoing both annulation and allylation reactions.
亚甲硅烷插入烯丙基醚发生在表面上以提供对映体富集的烯丙基硅烷和乙硅烷。利用银和铜介导的条件将亚甲硅烷插入各种受保护的烯丙醇被证明是形成烯丙硅烷的通用方法。烯丙基乙硅烷的反应与烯丙基硅烷类似,同时发生环化和烯丙基化反应。
