The solid acid, tin hydroxide-embedded montmorillonite, catalyzes the unprecedented alkylation of various silicon enolates with primary, secondary and tertiary benzylic alcohols as well as secondary allylic alcohols. The acid catalysis of Sn-Mont was not only higher than that of the other ion-exchanged montmorillonites (M-Mont; M=H, Ti, Fe and Al), but also higher than that of the typical homogeneous acid catalysts such as BF₃·OEt₂, TMSOTf and TfOH.

嵌入氢氧化锡的蒙脱石催化的碳正离子形成烯醇硅与醇的前所未有的烷基化反应

固体酸，氢氧化锡包埋的蒙脱石可催化各种烯醇硅与伯，仲和叔苄醇以及仲烯丙基醇的空前烷基化。Sn-Mont的酸催化作用不仅高于其他离子交换的蒙脱土（M-Mont； M = H，Ti，Fe和Al），而且高于典型的均相酸催化剂（如BF）₃ ·OEt ₂，TMSOTf和TfOH。
