Lett.: new type of photoexcitable alkylborate to generate functionalized alkyl radical. A new type of alkylborate was developed for the purpose of generating radicals via direct photo-excitation. 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 organoboron compounds is a significant advantage of this direct photo-excitation protocol. The excited states of these borates can also serve as strong reductants enabling various transformations.
