is applicable to variant alkylarylethers such as eugenol, vanillin, ortho-vanillin and methyl eugenol. Suitable substrates are not limited to alkyl o-hydroxyphenyl ethers. A practical procedure for the cleavage of alkylarylethers containing labile functional groups has been developed using aluminum triiodide as the ether cleaving reagent. Carbodiimides, typically used as dehydration reagents for
