Recent Advances in Arylations and Sulfonylations of Arylazo Sulfones

Aromatic ring-and sulfone-containing compounds are widely used in the fields of synthetic chemistry, medicinal chemistry and material chemistry.Therefore, it is of great significance to develop a simple, green and efficient method to construct aryl and sulfonyl compounds.Arylazo sulfones can be used as arylation or sulfonylation reagents to access aryl and sulfonyl compounds via hemolytic cleavage of C-N and N-S bonds to generate aryl radical and sulfonyl radical.In this review, the recent research progress of arylations and sulfonylations using arylazo sulfones is summarized.The synthetic methods and the related reaction mechanisms are highlighted, and an outlook of this research field is also given.
