Abstract

Acid-treated K10 montmorillonite (H-K10 mont) exhibited an outstanding catalytic activity in the nucleophilic substitution of propargylic alcohols with alkynylsilanes. The reactions were carried out under solvent-free conditions, and the solid catalyst was reusable with retention of its high activity. This method provides a green and rapid route to 1,4-diynes.
