And the article was published in Molecules in 2021. Safety of 2,4,6-Tris(diphenylamino)-3,5-difluorobenzonitrile The author mentioned the following in the article:
A reaction of aromatic halides bearing electron-withdrawing groups with tertiary amines in the presence of an iridium catalyst under blue light irradiation is described. Products of the aromatic substitution of the halide by the dialkylamino fragment are obtained. The interaction of aryl radicals with tertiary amines to generate zwitterionic radical species is believed to be the key factor responsible for the reaction efficiency. 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
