Xia, Hongyu published the artcileVisible Light Induced Aerobic Coupling of Arylboronic Acids Promoted by Hydrazone, Category: pyridine-derivatives, the publication is Advanced Synthesis & Catalysis (2022), 364(5), 922-929, database is CAplus.
A visible-light-induced oxidative coupling of arylboronic acids was developed for the synthesis of biaryls Ar1Ar2 [Ar1 = Ar2 = Ph, 4-MeC6H4, 4-FC6H4, etc.; Ar1 = 4-BrC6H4, 4-MeC6H4, 4-FC6H4, etc.; Ar2 = 4-H(O)CC6H4, 3-MeOC6H4, 4-AcC6H4, etc.]. The reaction that employed polydentate hydrazones as the bifunctional catalyst works smoothly under room temperature It was compatible with a wide range of functional group. The study of UV-Vis spectrum indicated that hydrazone and its complex with CuI show major absorptions upon visible-light, which secures the dual role of hydrazone as both ligand and photocatalyst in this reaction. Hence, the reaction was proposed to involve stepwise transmetallations, photo-induced oxidations, and reductive elimination.
