FeCl3 and FeCl3-SiO2 Catalysed Selective p-Methoxybenzylation of Alcohols with p-Methoxybenzyl Alcohol (PMB-OH)&#

摘要

Anhydrous FeCl3 and FeCl3-SiO2 serve as Lewis acids for direct conversion of alcohols into pmethoxybezyl ethers using PMB-OH in good yields, the latter reagent was found to be effective in not only converting primary, allylic and propargylic alcohols selectively but also the pre-existing acid sensitive groups remained unscathed.
