Direct vicinal sulfonyloximation of alkenes: an efficient and straightforward approach towards the synthesis of α-sulfonyl ketoximes.

Direct vicinal sulfonylative difunctionalization of simple alkenes represents a powerful strategy for the rapid assembly of β-functionalized sulfones from simple starting materials. In this context, the direct sulfonyloximation of alkene substrates has recently received much attention from the chemical community owing to important applications of α-sulfonyl ketoxime products in organic synthesis. This review provides an overview of recent research on the titled reactions, with an emphasis on the reaction patterns and mechanisms. Literature has been surveyed until the end of 2024.
