Electrooxidative Activation of B−B Bond in B₂cat₂: Access to gem‐Diborylalkanes via Paired Electrolysis

Angewandte Chemie International Edition, Journal Year: 2023, Volume and Issue: 62(14)

Published: Feb. 1, 2023

This report describes the unprecedented electrooxidation of a solvent (e.g., DMF)-ligated B2 cat2 complex, whereby solvent-stabilized boryl radical is formed via quasi-homolytic cleavage B-B bond in DMF-ligated cation. Cyclic voltammetry and density functional theory provide evidence to support this novel activation strategy. Furthermore, strategy for electrochemical gem-diborylation gem-bromides paired electrolysis developed first time, affording range versatile gem-diborylalkanes, which are widely used synthetic society. Notably, reaction approach scalable, transition-metal-free, requires no external activator.

Abstract This report describes the unprecedented electrooxidation of a solvent (e.g., DMF)‐ligated B 2 cat complex, whereby solvent‐stabilized boryl radical is formed via quasi‐homolytic cleavage B−B bond in DMF‐ligated cation. Cyclic voltammetry and density functional theory provide evidence to support this novel activation strategy. Furthermore, strategy for electrochemical gem ‐diborylation ‐bromides paired electrolysis developed first time, affording range versatile ‐diborylalkanes, which are widely used synthetic society. Notably, reaction approach scalable, transition‐metal‐free, requires no external activator.
