Item Bismuth(III) oxide perchlorate promoted rearrangement of epoxides to aldehydes and ketones(2012-11-14) Andrew M. Anderson; Jesse M. Blazek; Parie Garg; Brian J. Payne; Ram S. MohanAryl-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 inexpensive, making this catalyst an attractive alternative to more corrosive and toxic Lewis acids such as BF3 Et2O or InCl3 currently used to effect epoxide rearrangements. © 2000 Elsevier Science Ltd.
