The intramolecular hydroalkoxylation of gem-difluorinated alkynols was found possible under Au catalysis, allowing for the preparation of a series of fluorinated heterocycles. The nature of the solvent was found to be especially critical in the cycli

C-F bond activation has drawn a lot of attention in the past, and the case of C(sp3)-F bonds is particularly interesting as those are the strongest single bonds carbon makes with any other element. This Feature Article aims at highlighting our work a

We report that aromatic propargylation is achievable with secondary propargylic fluorides, thus affording 1-alkyl-1-aryl-2-alkynes. In the present case, hydrogen bonding is responsible for the activation of the C–F bond. A large excess of arene nuc

Herein, we report a highly regioselective gold-catalyzed formal hydration of propargylic gem-difluorides. Not only does this transformation provide access to versatile fluorinated building blocks that were difficult or hardly possible to access befor

The synthesis of monofluoroalkenes using a Pt-catalyzed amination reaction of cyclic 3,3-difluoropropenes is reported. The use of secondary aliphatic amines and cyclic 3,3-difluoropropenes is necessary for the success of the reaction.

The superior nucleofuge character of chlorine over fluorine was taken advantage of in the selective SN2′ substitution reaction of gem-chlorofluoropropenes, allowing for the clean formation of β-substituted monofluoroalkenes under metal-free condit
