Abstract :
Sulfonic acid functionalized ordered nanoporous sodium montmorillonite was easily prepared by the reaction of
sodium montmorillonite with chlorosulfonic acid. The new catalyst demonstrated efficient and chemoselective
methoxymethylation reaction of alcohols with formaldehyde dimethyl acetal in chloroform under reflux conditions.
This reaction affords corresponding ethers in good to excellent yields. The present method offers several
advantages such as short reaction times, high yields, simple procedure, mild conditions, heterogeneous nature, and
reusability of the catalyst.
