Organoboron Compounds in Visible Light-driven Photoredox Catalysis

The increasing importance of visible light photoredox catalysis as a powerful strategy for the activation of small molecules require the development of new effective radical sources and photocatalysts. The unique properties of organoboron compounds have contributed significantly to the rapid progress of photocatalysis. Since the first work on the topic in 2005, many researchers have appreciated the role of boron-containing compounds in photocatalysis, and this is reflected in several publications. In this review, we highlight the utility of organoboron compounds in various photocatalytic reactions enabling the construction of carbon- carbon and carbon-heteroatom bonds. The dual role of organoboron compounds in photocatalysis is highlighted by their applications as reactants and as well as organic photocatalysts.
