โฆ Synopsis
An efficient and selective method for the conversion ofallylic, secondary-and tertiary benzylic alcohols into their corresponding ethers in the presence of iron(III) as FeCI3 and Fe(C104)3 under solvolytic condition is described. The results obtained from an optically active allylic alcohol show that a carbonium ion is formed during the course of the reaction.
