An Efficient One-Pot Conversion of THP- and TMS Ethers to Sulfonate Esters Using FeCl₃-Montmorillonite K-10 Clay

Abstract

Various tetrahydropyranyl and trimethylsilyl ethers are efficiently transformed into the corresponding sulfonate esters with sulfonyl chlorides in the presence of FeCl 3 -Montmorillonite K-10 clay.

An Efficient Organocatalyzed Interconversion of Silyl Ethers to Tosylates Using DBU and p-Toluenesulfonyl Fluoride

“…Despite obvious advantages offered by such an interconversion strategy, only one procedure using a catalytic heterogenous system (FeCl 3 -Montmorillonite K-10) to convert aliphatic TMS ethers to sulfonate esters has been described in the literature. 3 We whish to report herein an efficient, mild, and high-yielding organocatalytic process to realize this useful interconversion.…”
