Aromatic C-Heteroatom Bond Formation

Iron (III) chloride is a common catalyst used in electrophilic aromatic substitutions. In addition to those applications outlined above for the construction of aromatic C-C bonds, such salts have also been used for the introduction of heteroatom-based functional groups at the aromatic ring [47]. 

In 2000, Takata et al. reported the synthesis of diaryIsulfoximines by the Friedel-Craft reaction of sulfonimidoyl chloride with aromatic compounds in the presence of
