Hypervalent iodine compounds (HVI) are well-established reagents for synthetic chemists. They are portrayed as an alternative to otherwise hazardous transition metals. This is due to their great reactivity in electrophilic group transfers , photoor organocatalysis , and their utility as building blocks for the synthesis of natural products . One subclass of HVIs is diaryliodonium salts (DIS), which have been used as versatile electrophilic arylation reagents in metal-catalyzed and metal-free reactions . The corresponding cyclic diaryliodonium salts (CDIS) have also been investigated as useful building blocks for the synthesis of larger diaryl-based molecules, (hetero)aromatic tricyclic systems, or new aryl-moieties . Most methods that generate DIS utilize iodoarenes as starting materials . In these one-pot procedures, iodoarenes react with nucleophilic arenes under oxidative acidic conditions.The synthesis of CDIS is more challenging since the arene moiety must be covalently connected to the iodoarene prior to cyclization. Recently, we published two new methods that describe the generation of carbon-and heteroatom-bridged CDIS . Herein, we improved the formation of iodoarenes through a Brønsted acidmediated Friedel-Crafts reaction followed by an oxidative cyclization to form the desired CDIS 1 (Scheme 1, A). This one-pot approach is based on ortho-iodinated benzyl alcohols as starting materials. It allows access to a variety of otherwise tedious to synthesize CDIS robustly in short reaction times. A significant drawback still is the use of stoichiometric amounts of chemical oxidants, which decreases the atom economy and necessitates additional workup procedures. A possible solution is the anodic oxidation of iodoarenes as electrochemistry is a highly economical tool that avoids chemical oxidants for synthesizing hypervalent iodine reagents . Iodoarenes are suitable and well-established mediators in either in-or ex-cell electrochemical processes .
