Recent Advances in Diaryliodonium Salts (II): Structures, Syntheses, and Reactivity

Abstract

Diaryliodonium salts have been widely employed as highly efficient electrophilic reagents in organic synthesis, owing to their high reactivity and excellent selectivity across a broad range of transformations. Over the past 5 years, considerable advances have been achieved in diaryliodonium chemistry. This review briefly summarizes the structural classes of diaryliodonium salts, their synthetic methods, and their reactivity in arylation reactions. As a continuation of the theme of our previous review, particular emphasis is placed on the new structural features of diaryliodonium salts and their syntheses.
