Abstract

<div class="line" id="line-15"> Aryl-substituted epoxides and aliphatic epoxides with a tertiary epoxide carbon undergo smooth rearrangement in the presence of 10&ndash;50 mol% bismuth(III) oxide perchlorate, BiOClO4&bull;xH2O, to give carbonyl compounds. The rearrangement is regioselective with aryl substituted epoxides and a single carbonyl compound arising from cleavage of benzylic C&horbar;O bond is formed. BiOClO4&bull;xH2O is relatively non-toxic, insensitive to air and inexpensive, making this catalyst an attractive alternative to more corrosive and toxic Lewis acids such as BF3&bull;Et2O or InCl3 currently used to effect epoxide rearrangements.</div>
