Abstract

1,1-Difunctionalization of α‑carbonyl sulfur ylides and thiosulfonates under simple conditions is disclosed. In this protocol, two new C–S bonds are constructed in a one-step reaction. A series of aliphatic and aromatic β-keto thiosulfones were obtained in moderate to good yields. This reaction probably proceeds through sulfur ylide-involved­ nucleophilic substitution of an ion pair within a solvent cage.
