Highly reactive gold vinylidene species are used for intermolecular C(sp3)H insertions into unactivated alkanes (see scheme). In addition, they can be regarded as synthons for alkylidene carbenes. Initiated by cyclopropanation of the vinylidene species/alkylidene carbenoide, cyclobutene derivatives are formed in a diastereoselective fashion by a ring‐enlargement cascade in only one step.
高反应性的亚乙烯基金物质用于将C(sp 3)H分子间插入未活化的烷烃中(请参阅方案)。另外,它们可以被视为亚烷基卡宾的合成子。通过亚乙烯基物质/亚烷基碳烯化物的环丙烷化反应,仅需一步就可以通过扩环级联以非对映选择性的方式形成环丁烯衍生物。
