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.

A redox-neutral, mild, and simple protocol is developed for the synthesis of [small alpha]-trifluoromethylated ketonesfromvinyl azides under transition-metal-free conditions. In the presence of organic photoredox catalyst N-methyl-9-mesityl acridinium and...
The present invention relates to a group of compounds which are novel substituted alkyl piperidines and which act to inhibit the synthesis of cholesterol in mammals and in fungi.

We present herein a pyridinium-masked enol as a versatile platform to produce ketones bearing tri-, di-, and monofluoromethyl in the presence of [Ir(dF(Me)ppy)]2(dtbbpy)]PF6 under blue light (455 nm) irradiation. By simply changing the F-source, α-trifluoromethyl ketones, α-difluoromethyl ketones, and α-monofluoromethyl ketones could be easily prepared in moderate to excellent yields in one step, making
