Photochem. organocatalytic substitution of pyridylthio group in alkyl tetrafluoropyridinyl thioethers RS-4-C5F4N with bis(catecholato)diboron followed by treatment with pinacol and triethylamine affording pinacol boronic esters RBpin is described. The reaction is promoted by an organic photocatalyst, 2,4,6-tris(diphenylamino)-3,5-difluorobenzonitrile (3DPA2FBN) under irradiation with 400 nm light, and works with primary, secondary, and tertiary sulfides. The electron depleting character of the fluorinated pyridine fragment plays an important role in generating alkyl radicals. In the experiment, the researchers used many compounds, for example, 2,4,6-Tris(diphenylamino)-3,5-difluorobenzonitrile(cas: 1403850-00-9Safety of 2,4,6-Tris(diphenylamino)-3,5-difluorobenzonitrile)
2,4,6-Tris(diphenylamino)-3,5-difluorobenzonitrile(cas: 1403850-00-9) is cyanoarene-based donor-acceptor photocatalyst developed by the Zeitler group. While this catalyst has a balanced redox profile, allowing for its use in a variety of transformations, it stands out as the most reducing catalyst of the family.Safety of 2,4,6-Tris(diphenylamino)-3,5-difluorobenzonitrile
