Distal iodine migration of arylalkynes via cyclic monoaryliodonium salts

Abstract

Disclosed herein is a novel protocol for the synthesis of cyclic monoaryliodonium salts (CMAIs) from readily available iodoethynylarenes. The tandem one-pot iodine migration of iodoethynylarenes via the generation of these...

Palladium-Catalyzed Triple Suzuki–Miyaura Reactions Using Cyclic (Vinyl Triflate)iodonium Salts

“…Additionally, when the aromatic component is benzoic acid, the OTf can be replaced by azide to generate pseudocyclic derivatives. As shown in Scheme b, cyclic (vinyl triflate)­iodonium salts have been highlighted in recent reports . The preparation of these salts involves the activation of the aryl C–H bond through oxidation, leading to the formation of cyclic hypervalent iodoniums.…”
