Deuteriodifluoromethythio (SCF2D) and deuteriodifluoromethyl (CF2D) are important functional groups in pharmaceutical and agrochemical compounds, and the introduction of these functional groups remains a challenging. We herein report a robust reagent for deuteriodifluoromethylthiolation and deuteriodifluoromethylation. Its potentials were successfully showcased by deuteriodifluoromethylation and deuteriodifluoromethylthiolation of indoles with high-level deuterium incorporation. The reagent also has potential for deuteriodifluoromethylation and deuteriodifluoromethylthiolation of wide range of other natural or synthetic bioactive molecules.

A general and facile synthetic method for β-fluoroenones from silyl enol ethers or ketones, with a copper-amine catalyst system, has been developed. The reaction proceeded by a tandem process of difluoroalkylation-hydrolysis-dehydrofluorination. This method is characterized by high yields, excellent Z/E ratios, a low-cost catalyst, and a broad substrate scope. The synthetic potential of β-fluoroenones has been demonstrated by the construction of various complicated organofluorine molecules.
