Benzyl acetates undergo smooth deoxygenative allylation with allyltrimethylsilane in the presence of 10 mol % of molecular iodine under mild conditions to afford the corresponding allyl derivatives in excellent yields and with high selectivity. Cinnamyl alcohols also react readily with allylsilane under similar conditions. The use of molecular iodine makes this method quite simple, more convenient
在温和条件下,在 10 mol% 分子碘的存在下,乙酸苄酯与烯丙基三甲基硅烷发生平稳的脱氧烯丙基化反应,以优异的产率和高选择性得到相应的烯丙基衍生物。肉桂醇在类似条件下也很容易与烯丙基硅烷反应。分子碘的使用使该方法变得非常简单、方便且经济有效。
