Bismuth(III) trifluoromethanesulfonate [Bi(OTf)₃] mediated mild electrophilic aromatic formylation utilizing difluoro(phenylsulfanyl)methane (PhSCF₂H) as a formylating agent in hexafluoro‐2‐propanol (HFIP) as a recyclable ionizing solvent has been developed. The active formylating species was generated via C−F bond cleavage and was characterized to be a bis(phenylsulfanyl)methyl cation by experimental and computational ¹H and ¹³C NMR.

HFIP中具有Bi（OTf）3的C-F键断裂：用二氟（苯硫基）甲烷进行亲电芳构化

三氟甲烷磺酸铋（III）[Bi（OTf）₃ ]介导了温和的亲电芳族甲酰化反应，利用二氟（苯基硫烷基）甲烷（PhSCF ₂ H）作为甲酰化剂在六氟-2-丙醇（HFIP）中作为可循环电离溶剂。活性的甲酰化物质是通过CF键断裂而生成的，并通过实验和计算的¹ H和¹³ C NMR表征为双（苯基硫烷基）甲基阳离子。
