Direct synthesis of fluorinated heteroarylether bioisosteres
(Bioiso)steering in a new direction: A modular synthesis of reagents (e.g. sodium difluoroethylsulfinate) that can be used for the direct incorporation of difluoroalkyl groups onto heterocycles is reported. The scope and generality of the incorporation of

Radical Fluoroalkylation of Isocyanides with Fluorinated Sulfones by Visible-Light Photoredox Catalysis
The radical fluoroalkylation of isocyanides with fluorinated sulfones is enabled by visible-light photoredox catalysis. A wide range of readily available mono-, di-, and trifluoromethyl heteroaryl sulfones can thus be used as efficient radical fluoroalkylation reagents under mild conditions. This method not only describes a new synthetic application of fluorinated sulfones, but also provides a new route to fluoroalkyl radicals.

Modified Julia olefination on sugar-derived lactones: Synthesis of difluoro exo-glycals
We report the preparation of difluoro-exo-glycals by gem-difluoroolefination of benzylated sugar-derived lactones using a modified Julia reaction. The addition is highly stereo-selective, and the Smiles-rearrangement-elimination sequence can be carried out under microwave irradiation.

From difluoromethyl 2-pyridyl sulfone to difluorinated sulfonates: A protocol for nucleophilic difluoro(sulfonato)methylation
An efficient method for the synthesis of alkyl α,α- difluorosulfonates has been developed. The selection of the 2-pyridyl group as the aryl substitute on the sulfone is critically important for the success of this transformation (see scheme). The synthetic application of fluorinated sulfones is extended and a unique solution is provided for a long-standing challenge in nucleophilic difluoro(sulfonato)methylation reactions. Copyright

Difluoromethyl 2-pyridyl sulfone: A new gem-difluoroolefination reagent for aldehydes and ketones
Chemical equation presented Difluoromethyl 2-pyridyl sulfone, a previously unknown compound, was found to act as a novel and efficient gem-difluoroolefination reagent for both aldehydes and ketones. It was found that the fluorinated sulfinate intermediate in the reaction is relatively stable, which can be observed by 19F NMR and trapped with CH 3l.
