A desulfonylative homocoupling of benzylic sulfone derivatives through a photoredox Ir catalyst is described. The 3,5-bis(trifluoromethyl)phenyl group is an effective substituent on sulfonyl group in this reaction, providing the structurally diverse multiply arylated ethanes in good yields. The α-deuterated or α-fluorinated sulfones, which can be readily prepared by α-functionalization, were also applicable
描述了通过光氧化还原 Ir 催化剂对苄基砜衍生物进行脱磺酰化同偶联。在该反应中,3,5-双(三氟甲基)苯基是磺酰基上的有效取代基,以良好的收率提供结构多样的多芳基化乙烷。α- 氘代或 α- 氟化的砜,可以很容易地通过 α 官能化制备,也适用,突出了合成药用重要结构的途径。
