Article Abstract
Fluoroalkenes represent a useful class of peptidomimetics with distinct biophysical properties. Current preparations of this functional group commonly provide mixtures of E- or Z-fluoroalkene diastereomers, and/or mixtures of nonfluorinated products. To directly access fluoroalkenes in good stereoselectivity, a Shapiro fluorination reaction was developed. Fluoroalkene products were accessed in one- or two-step sequences from widely available ketones. This strategy should be useful for the preparation of fluorinated analogs of peptide-based therapeutics, many of which would be challenging to prepare by alternate strategies.

We have developed an efficient synthesis of fluoroalkenes via tandem electrochemical dehalogenation-elimination protocol. The key step is the generation of carbon anion by electrochemical reductive dehalogenation of alkyl halides. Various gem-difluoroalkenes and monofluoroalkenes were prepared in moderate to good yields from α-difluoromethylated/α-trifluoromethylated benzyl halides.

In this study, we develop the synthesis methods of fluoroalkenes and fluoroenynes via Suzuki-Miyaura and Sonogashira cross-coupling reactions using novel multihalogenated fluorovinyl ethers, which are easily prepared from the reaction between phenols and 2-bromo-2-chloro-1,1,1-trifluoroethane (halothane). These reactions make use of the unique structure of multihalogenated fluorovinyl ethers, which contains a reactive bromine atom, to afford a series of fluoroalkenes and fluoroenynes in moderate to high yields.

Organofluorines have a broad range of industrial applications, such as pharmaceuticals, liquid crystal displays (LCDs), solar cells, textiles, and construction coatings, and are used in peptidomimetics, surfactants, refrigerants, anesthetics, and agrochemicals. Among them are versatile monofluoroalkenes that play a crucial role in medicinal and synthetic chemistry. The synthetic strategies for this class of molecules are limited, and prior efforts frequently suffered from poor atom- and step-economies.

Controlled radical copolymerizations present attractive avenues to obtain polymers with complicated compositions and sequences. In this work, we report the development of a visible-light-driven organocatalyzed controlled copolymerization of fluoroalkenes and acyclic N-vinylamides for the first time. The approach enables the on-demand synthesis of a broad scope of amide-functionalized main-chain fluoropolymers via novel fluorinated thiocarbamates, facilitating regulations over chemical compositions and alternating fractions by rationally selecting comonomer pairs and ratios.
