Dithianylium salts in combination with oxidative fluorodesulfuration chemistry act as a versatile new class of α,α-difluoroalkylation reagents, allowing for the first time the convenient synthesis of complex α,α-difluoroethers or α-fluoroacetals. Even relatively fragile species, such as α,α-difluoroalkyl azides or peroxides, can be obtained under very mild reaction conditions. (© Wiley-VCH Verlag GmbH
二噻吩盐与氧化性氟脱硫化学相结合,作为一类多功能的新型 α,α-二氟烷基化试剂,首次允许方便地合成复杂的 α,α-二氟醚或 α-氟缩醛。即使是相对脆弱的物质,如 α,α-二氟烷基叠氮化物或过氧化物,也可以在非常温和的反应条件下获得。(© Wiley-VCH Verlag GmbH, 69451 Weinheim, Germany, 2002)
