We present a rapid (0.25–1 h), method to produce functionalised allylsilanes from readily available vinylsilanes. Employing a Brønsted acid catalysed dehydration as the key step, allylsilanes are produced in good yields (22–98%) and, in most cases, as a single geometric isomer. Furthermore, a possible allylation-Cope pathway was discovered for certain substrates and attempts to optimise this are described
我们提出了一种从容易获得的乙烯基硅烷中快速(0.25-1 小时)生产官能化烯丙基硅烷的方法。采用布朗斯台德酸催化脱水作为关键步骤,烯丙基硅烷的产率很高 (22-98%),并且在大多数情况下,以单一几何异构体的形式生产。此外,还发现了某些底物可能的烯丙基化-Cope 途径,并描述了对其进行优化的尝试。
