substitution of the phenyl group with a hydroxy group took place smoothly to afford alkenylsilanol derivatives in good yields. The reaction mechanism was investigated using 18 O-labeled sulfoxide. We found that a (methylsulfinyl)methyl anion generated from DMSO participated in this reaction.
在 DMSO 中用 t-BuOK 和 18-crown-6 处理烯丙基苯基硅烷时,烯烃双键的异构化和随后的苯基被羟基取代的过程顺利进行,以良好的产率得到烯基硅烷醇衍生物。使用 18 O-标记的亚砜研究了反应机理。我们发现由 DMSO 产生的(甲基亚磺酰基)甲基阴离子参与了该反应。
