Recent Advances in Photoinduced Borylation via N-Heterocyclic Carbene Boryl Radicals

Organoboron compounds, recognized as essential synthetic intermediates in organic chemistry, have found broad applications in pharmaceutical and materials science. In recent years, the development of novel boronating reagents has opened new avenues for the synthesis of organoboron. Among these, NHC–boranes, with their unique advantages, have garnered sustained interest and have evolved into significant precursors for boron-centered radicals, participating in a diverse array of visible light-induced borylation reactions. This article primarily focuses on the visible light-induced radical borylation reactions involving NHC–boranes, summarizing the latest advancements in the field, and offering inspiration for subsequent research.
