Organic photoredox-catalyzed oxidative azolation of unactivated fluoroarenes

Organic & Biomolecular Chemistry, Journal Year: 2023, Volume and Issue: 21(32), P. 6503 - 6508

Published: Jan. 1, 2023

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, Journal Year: 2024, Volume and Issue: 26(28), P. 5923 - 5927

Published: July 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.
