Inexpensive and commercially available 2,4,6-triphenylpyrrolium tetrafluoroborate (TPT) is used as an organic photocatalyst for the nucleophilic aromatic substitution of unactivated fluoroarenes with pyrazole derivatives (SNAr) to form azole arenes. The use photoredox catalysis enables easy operation this method under mild conditions. Various fluorinated compounds are suitable electrophiles transformation.

Photocatalytic Proficiency of Cinnoline Moiety for Cross-Coupling Reactions: A Two in One Photocatalyst

Organic Letters, Год журнала: 2024, Номер 26(28), С. 5923 - 5927

Опубликована: Июль 3, 2024

Herein, we have developed a new class of organic photocatalysts that can mimic transition metals for several oxidative and reductive cross-coupling transformations. Due to its wide potential window in both the oxidation reduction ranges, cinnoline exhibits dual catalytic activity under visible light illumination, acting as photoreductant photooxidant.
