2,3-sigmatropic rearrangement

2,3-Sigmatropic rearrangements are a type of sigmatropic rearrangements and can be classified into two types. Rearrangements of allylic sulfoxides, amine oxides, selenoxides are neutral. Rearrangements of carbanions of allyl ethers are anionic. The general scheme for this kind of rearrangement is: A [2,3]-rearrangement may result in carbon-carbon bond formation. It can also be used as a ring-expansion reaction.
