Abstract Recently, electrochemical methods have been harnessed as a transition metal‐free strategy for borylation reactions in the synthesis of organoboron compounds. This article reviews C−C and C−Het bonds, offering systematic discussion C−C, C−N, C−O, C−S bond reactions. These transformations are applied to substrates including ammonium salts, aryl azo sulfones, carboxylic acids, arylhydrazines, nitroarenes, alcohols, thioethers, showcasing broad compatibility. Additionally, review discusses reaction mechanisms, scalability, practical applications these strategies. The concludes by outlining future research directions reactions, aiming at expending their incorporating boron into wider array organic compounds, challenging unactivated C−F borylations.

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

ChemPhotoChem, Год журнала: 2025, Номер unknown

Опубликована: Май 25, 2025

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

Formate‐Mediated Synthesis of β‐Hydroxysulfides from Olefins and Thiosulfonates via EDA Complex Strategy under Visible Light Irradiation in Air

Chinese Journal of Chemistry, Год журнала: 2024, Номер 42(23), С. 3129 - 3134

Опубликована: Авг. 13, 2024

Comprehensive Summary A visible‐light‐induced and efficient one‐pot synthesis of β ‐hydroxysulfides from olefins, thiosulfonates HCOOCs using an EDA complex strategy under air atmosphere at room temperature has been disclosed. plausible radical involved mechanism is proposed. During the reaction process, formates play a crucial role: first, as donors in complex; second, providers hydrogen source; third, by generating CO 2 •– to reduce peroxide intermediates, leading formation ‐hydroxysulfides. In contrast previously reported thiol‐oxygen co‐oxidation reactions, this simple sustainable approach features mild conditions, operational simplicity, odorless excellent functional group tolerance.

Abstract This research article uses density functional theory (DFT) to study photoinduced borylation. work examined the electron donor‐acceptor complex (EDA) of bis(catecholato)diboron with different redox‐active leaving groups and bis(pinacol)diboron aryl N‐hydroxyphthalimide. The results these DFT studies show ratio B 2 cat N, N‐dimethylacetamide (DMA) should be 1 : which is consistent experimental in literature. We further proposed a reaction mechanism calculated energies associated each step.
