perfluoroalkyl iodides with silyl enol ethers mediated by Et3B in the presence of base such as 2,6-dimethylpyridine provides mixtures of perfluoroalkylated trialkylsilyl enol ethers and α-perfluoroalkylated ketones. The yield and distribution of the products heavily depend on the nature of base employed. Treatment of a reaction mixture consisting of perfluoroalkylated silyl enol ether and α-perfluoroalkylated
Reaction of perfluoroalkyl iodides with silyl enol ethers mediated by Et3B in the presence of a base provides perfluoroalkylated silyl enol ethers. Meanwhile, treatment of germyl enol ethers with perfluoroalkyl iodides affords β-perfluoroalkyl ketones in good yields.
