Au(I)/Au(III)-Catalyzed\nSulfonylation of Aryl Iodides\nfor the Synthesis of Various Functionalized Aryl Sulfones

A gold-catalyzed sulfonylation reaction of aryl iodides\nwith different\nsodium sulfinates facilitated by the ligand-enabled Au(I)/Au(III)\nredox catalysis was developed. In the reaction of gold-catalyzed C–S\ncoupling, a variety of functionalized sodium sulfinates, such as CF<sub>3</sub>, CHF<sub>2</sub>, CH<sub>3</sub>, and alkyl groups, can react\nsmoothly with aryl iodides to directly construct diversely functionalized\naryl sulfones. This gold-catalyzed sulfonylation offers a complementary\nmethod for synthesizing functionalized aryl sulfones with electron-donating\ngroups.
