Shang, Tianbo published the artcilePhotocatalytic Remote Oxyfluoroalkylation of Heteroalkynes: Regio-, Stereo-, and Site-Selective Access to Complex Fluoroalkylated (Z)-Alkenes, Safety of Ethylbromofluoroacetate, the publication is Organic Letters (2020), 22(9), 3667-3672, database is CAplus and MEDLINE.
A visible-light-induced remote oxyfluoroalkylation, including ketofluoroalkylation and hydroxytrifluoromethylation, of heteroalkynes is developed with DMSO (DMSO) and H2O as the oxygen source, resp. It provides a facile access to complex fluoroalkylated (Z)-alkenes in satisfactory yields with excellent regio-, stereo-, and site-selectivity. The reaction involves an uncommon vinyl radical-induced intermol. C(sp3)-H functionalization, thus offering a good platform for the development of remote difunctionalization of alkynes.
