Fluorinated compounds have gained much attention because of their unique electronegativity, metabolic stability and bioavailability, and thus, the synthesis of organofluorine compounds has found wide applications in pharmaceuticals, agrochemicals, and materials science. Among them, the incorporation of a difluoromethyl group (CF₂) into organic compounds is of great concern in medicinal chemistry owing to its isosterism with the hydroxyl group. Therefore, the development of new difluoroalkylation methods has attracted great interest in synthetic organic chemistry. Visible light-driven photocatalysis as an eco-friendly and powerful theme has been widely utilized in organic synthesis. In particular, free radical fluorination is emerging as a powerful tool for C-F bond formation, especially under the catalysis of visible light. Recent progress on the visible light-promoted directing difluoroalkylation using ethyl bromodifluoroacetate provided an efficient approach to the target. Herein, we report a contribution towards visible light induced carbodifluoroalkylation of homopropargylic alcohols with the use of ethyl bromodifluoroacetate as a source of difluorinated moieties. This strategy provides a facile way to access functional-difluorinated alkenes through a tandem radical difluoroalkylation and 1, 4-aryl migration process. A representative procedure for this reaction is as following:An oven-dried Schlenk tube (10 mL) was equipped with a magnetic stir bar, homopropargylic alcohols (0.2 mmol), fac-Ir (ppy)₃ (0.02 equiv., 0.004 mmol), 2-bromo-2, 2-difluoroacetate (2.5 equiv. 0.5 mmol), Na₂HPO₄ (2 equiv., 0.4 mmol). The flask was evacuated and backfilled with Ar for 3 times. 0.5 mL of dry DMA and 0.5 mL of dry DCE were added with syringe under Ar. The tube was placed at a distance (app. 5 cm) from 33 W fluorescent light bulb, and the resulting solution was stirred at ambient temperature under visible-light irradiation. After the reaction was finished, the mixture was then diluted with MTBE (20 mL×2) and water. The combined organic layers were dried over sodium sulfate and the solvent concentrated in vacuo and the residue was purified by chromatography on silica gel to afford the corresponding products.
