人们发现，锡离子交换蒙脱土（Sn-Mont）是一种强大的催化剂，可用于在空间拥挤的情况下与氰基三甲基硅烷进行具有羰基的芳香族和脂肪族酮的氰基甲硅烷基化反应，以优异的产率生成相应的氰醇三甲基甲硅烷基醚。
Tin ion-exchanged montmorillonite (Sn- Mont) was found to be a powerful catalyst for the cyanosilylation of aromatic and aliphatic ketones having a carbonyl group in sterically congested circumstances with cyanotrimethylsilane, giving the corresponding cyanohydrin trimethylsilyl ethers in excellent yields.
