Abstract

Imidoyl sulfoxonium ylides are presented for the first time as potential precursors to generate alpha-imino metal-carbene intermediates and applied in direct C-H functionalization reactions catalyzed by {[}Ir(cod)Cl](2) (4 mol %) to provide 2-substituted indoles (up to 70% yield) in just one step. This class of sulfur ylide is successfully obtained from imidoyl chloride and dimethylsulfoxonium methylide (23 new examples in 45-85% yield) or by imino group formation from the corresponding beta-keto sulfoxonium ylides and anilines in the presence of TiCl4 as a Lewis acid (9 examples in 33-94% yield).
