  Nucleophilic tetrafluoroethylation of carbonyl compounds with fluorinated sulfones

  摘要：

  Global interest in the "CF2CF2" building blocks (tetrafluoroethylene, tetrafluoroethyl) is still rather marginal. One of the main reasons is the lack of efficient and selective tetrafluoroethylation reagents. In this context, we present here three new reagents (PhSO2CF2CF2R, R = SiMe3, SiEt3 and H) capable of nucleophilic addition to carbonyl compounds, thus affording rare alcohols containing the CF2CF2 motif. The experimental observations are complemented with a brief computational study which confirmed that the reactivity of the nudeophilic reagents is strongly dependent on electronic properties of substituents on both ends of the CF2CF2 group.

  PhSCF2CF2SiMe3 (1) was developed as a tandem anion and radical tetrafluoroethylene equivalent for the introduction of a CF2CF2 moiety. Fluoride-initiated nucleophilic additions of 1 to carbonyl compounds provide the corresponding alcohol adducts 2. Reduction of 2 gives tetafluoroethyl-containing alcohols 3, whereas 6-exo radical cyclizations of allyl ethers 4 yield tetrafluorotetrahydropyrans 5.

  PhSCF2CF2SiMe3 (1) 被开发为串联阴离子和自由基四氟乙烯等价物，用于引入 CF2CF2 部分。1 与羰基化合物的氟化物引发的亲核加成提供相应的醇加合物 2。 2 的还原产生含四氟乙基的醇 3，而烯丙基醚 4 的 6-外自由基环化产生四氟四氢吡喃 5。
