Diaryl-A/’-iodanes

Ligand exchange of monoaryl-A -iodanes with an arylsilane or arylstannane leads to analogous diaryl reagents, which have unique uses. For example, diaryl-A -iodanes bring about a-arylation of enolates, as shown below ... 

Diaryl-A, -iodanes are well-known iodine(lll) compounds and can work as excellent electrophilic arylating agents because of the remarkable electron deficiency at iodine. Because of their relatively low cost and toxicity, they are promising substitutes for transition metal-based reagents [61]. 

Diaryl-A, -iodanes (often referred to as diaryliodonium salts) such as [PhjIJOTf or derivatives can couple the phenyl group with another aromatic ring to form a...
