CAN/[nbp]FeCl4 as a Reusable Catalytic System for Direct Conversion of Trimethylsilyl Ethers to Their Acetates Under Microwave Irradiation

A rapid and easy procedure for direct conversion of TMS-ethers to their acetates catalyzed by cerium(IV) ammonium nitrate (CAN) immobilized on n-butylpyridinium tetrachloroferrate ([nbp]FeCl4) as a room temperature ionic liquid under microwave irradiation was developed. This methodology is enough mild so that the acid sensitive groups such as methoxy, furyl or thiophenyl were remained intact. No side products were observed by this method
