Abstract

Various alcohol silyl ethers were readily and efficiently transformed into the corresponding alkyl ethers in high yields by the use of aldehydes combined with triethylsilane in the presence of a catalytic amount of iron(III) chloride.

Key words

silyl ether - alkyl ether - protecting group - iron(III) chloride - reductive etherification
