Recent Advances in Borylation via Electron Donor–Acceptor Complex Photoactivation

Abstract

Photoinduced borylation has been becoming a fascinating and growing research field in synthetic chemistry. On the other hand, electron donor‐acceptor (EDA) complex photoactivation has emerged as an alternative strategy to generate active open‐shell species without the need of photosensitizers. Suitable organoboron compounds can serve as the electron donor or acceptor to form the corresponding electron donor‐acceptor complexes, which then undergo photoinduced intra‐complex single electron transfer (SET) to generate carbon‐ or boron‐centered radicals for the construction of new C‐B bonds. In this Concept paper, we summarize the recent advances in photoinduced borylation via the EDA complex photoactivation strategy containing the related literature until December 2022.

A Computational Study of Photoinduced Borylation for Selected Boron Sources

“…[6] This kind of reaction can be started with an aryl chloride, [7] a photocatalyst [8][9][10][11] and also an electron donor acceptor complex (EDA) approach. [12][13][14][15][16] The EDA complex approach is not only limited to borylation, but also can be applied to a lot of different types of reactions. [17][18][19] EDA complex is a type of reaction where typically an additional absorption band will appear in the UV-Visible spectrum.…”
