Sulfonic acid-functionalized ordered nanoporous Na+-montmorillonite (SANM), is easily prepared by the reaction of Na+-montmorillonite with chlorosulfonic acid. This reagent acts as a highly efficient and reusable catalyst for the chemoselective trimethylsilylation of alcohols and phenols and deprotection of silyl ethers under mild and completely heterogeneous reaction conditions.
