electrooxidation of a solvent (e.g., DMF)-ligated B2cat2 complex, whereby a solvent-stabilized boryl radical is formed via quasi-homolytic cleavage of the B−Bbond in a DMF-ligated B2cat2 radical cation. Furthermore, a strategy for the electrochemical gem-diborylation of gem-bromides viapairedelectrolysis is developed for the first time, affording a range of versatile gem-diborylalkanes.
该报告描述了溶剂(例如 DMF)连接的 B 2 cat 2络合物前所未有的电氧化,由此通过 DMF 连接的 B 2 cat中B−B 键的准均裂裂解形成溶剂稳定的硼基自由基2自由基阳离子。此外,首次开发了一种通过配对电解对宝石-溴化物进行电化学宝石-二硼基化的策略,提供了一系列通用的宝石-二硼基烷烃。
