Photoinduced Electron Donor–Acceptor Complex-Enabled Transformations Involving Boron-Containing Compounds

Over the past decades, visible-light-driven reactions have emerged as a powerful tool in organic synthesis. Unlike traditional photoredox reactions that require additional catalysts or photosensitizers, electron donor–acceptor (EDA) complex-mediated photochemistry offers a simpler and more cost-effective approach to achieving diverse radical transformations without the need for noble catalysts. Among these, the use of boron-containing compounds as electron donors or acceptors in EDA complexes has garnered significant attention due to their unique properties. This review highlights recent advances in visible-light-induced EDA complex-mediated transformations involving boron-containing compounds, focusing on their applications in constructing CC and CB bonds and elucidating the underlying reaction mechanisms.
