27.1.3.2.7 Method 7: Rearrangement Reactions of Sulfonium Ylides

DOI: 10.1055/sos-SD-027-00002

Aggarwal, V.; Richardson, J.Science of Synthesis, (20042788.

The generation of sulfonium ylides in the presence of reactive electrophilic trapping reagents generally suppresses ylide rearrangements. However, in the absence of such species, ylide rearrangements often occur unless the ylide is sufficiently stabilized. Whilst rearrangement reactions of sulfonium ylides are frequently used in synthesis, they are also observed as competing processes with less rapid ylide reactions.
