Abstract

Reaction of perfluoroalkyl iodides with silyl enol ethers mediated by Et 3 B 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 ketone with coned HCl in THF ...
