Aryl-substituted epoxides and aliphatic epoxides with a tertiary epoxide carbon undergo smooth rearrangement in the presence of 10–50 mol% bismuth (III) oxide perchlorate, BiOClO4·× H2O, to give carbonyl compounds. The rearrangement is regioselective with aryl substituted epoxides and a single carbonyl compound arising from cleavage of benzylic C– O bond is formed. BiOClO4·× H2O is relatively non-toxic, insensitive to air and ...
