Advancements in the Synthesis of Diaryliodonium Salts: Updated Protocols
Erika Linde, Shobhan Mondal, Berit Olofsson
Abstract
Abstract Our group has reported several one‐pot protocols for the synthesis of diaryliodonium salts, which have been recognized as attractive multi‐purpose reagents in areas ranging from organic synthesis to materials chemistry. Over the years, we have identified limitations in the published protocols concerning synthesis of mixed electron‐rich and electron‐poor, as well as highly electron‐poor diaryliodonium salts, as the corresponding starting materials are either too reactive or too unreactive. In this update, we discuss the underlying limitations concerning the stability and reactivity of the involved reagents and provide strategies to overcome these challenges through updated synthetic protocols.
