While carbon-based iodonium salts have been well studied, their heteroatom-bridged counterparts are underrepresented due to the low availability of efficient synthetic protocols. The first synthesis of O-and N-bridged cyclic iodonium salts was developed by Behringer et al. (Scheme 1, a), starting from diphenylether or -amine scaffolds. In a two-step procedure, the corresponding oxidized iodane was isolated and subsequent cyclization of the oxidized intermediate with sulfuric acid gave the desired cyclic iodonium salts. Modern approaches towards iodaoxinium salts based on preexisting iodinated diarylethers have been described by Wen and Huber. Due to the growing interest of these reactive compounds, efficient and reliable procedures for their efficient synthesis are highly desirable.
