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.

parent ketone 2-methylcyclohexanone. Substitution of the methyl group on C(2) by a CF3-group strongly enhances bimolecular reactions such as reduction product formation in 2-propanol or oxetane formation in the presence of alkenes. We now report preliminary results on monomolecular photochemical reactions of several 2-(perfluoroalkyl)cycloalkanones.
Reaction of sodium perhalofluoroalkyl sulfinates with alkenes under UV irradiation and oxygen atmosphere provides α-perhalofluoroalkyl ketones in good yields.

2-Fluoroalkyl quinolines are prepared by reacting aniline with alpha-fluoroalkyl aldehydes or alpha-fluoroalkyl cyclohexanones in the presence of acetic acid. Under the same reaction condition, 2-aminophenol gives the corresponding 2-fluoroalkyl-8-quinolinols; in some cases, 2-fluoroalkyl benzoxazoles are also formed as minor products.
