was developed for the purpose of generating radicals via direct photoexcitation. These borates were prepared using 2,2′-(pyridine-2,6-diyl)diphenol as a tridentate ligand together with organoboronic acids or potassium trifluoroborates. The ready availability of organoboroncompounds is a significant advantage of this direct photoexcitation protocol. The excited states of these borates can also serve

An efficient photoredox-catalyzed three-component coupling reaction of aryl amine, glyoxalate and alkyltrifluoroborates has been reported. A variety of N-arylated aminoesters were constructed rapidly using an organic photocatalyst under mild conditions. Broad substrate scope and good functional group tolerance are the key features of this strategy.
