Silylene transfer to allylic sulfides results in a formal 1,2-sulfide migration. The rearrangement yields substituted silacyclobutanes, not the expected silacyclopropanes. The silacyclobutanes were elaborated by insertions of carbonyl compounds selectively into one carbon−silicon bond. A mechanism for the 1,2-sulfide migration is proposed involving an episulfonium ion intermediate.
亚甲硅烷转移到烯丙基硫化物会导致正式的 1,2-硫化物迁移。重排产生取代的硅杂环丁烷,而不是预期的硅杂环丙烷。硅杂环丁烷是通过将羰基化合物选择性地插入一个碳 - 硅键来制备的。提出了 1,2-硫化物迁移的机制,涉及环锍离子中间体。
