Benzenoid rings are found in consumer products that range from leading pharmaceuticals to liquid crystal displays, and, as such, the formation of new bonds to these scaffolds is an active area of chemical research.  Diaryliodonium salts are emerging as novel metal-free arylation reagents in this regard.  However, the trove of reactivity (ionic, radical, aryne) possible with these reagents is under utilized due to limited control over reaction pathways.  The discovery and development of metal-free arylation reactions will be discussed with an emphasis on regio-controlled aryl transfer from unsymmetrical aryl(auxiliary)iodonium salts.
