Abstract:
Charge-accelerated sigmatropic rearrangements are useful reactions for the creation of key C-C bonds in synthesis. In this mini-review, recent developments in sulfonium [3,3]-sigmatropic rearrangements that take place under mild and operationally simple conditions are presented and discussed in a unified manner.
