Pulsed electrosynthesis efficiently converts aromatic organoboron reagents to aryl radicals. Mechanistic studies reveal that pulsed electrosynthesis overcomes challenges like radical grafting/passivation, homocoupling, overoxidation, and decomposition. This electro-oxidative method enables straightforward functionalization of aromatic organoboron reagents to form aryl C−P, C−Se, C−Te, and C−S bonds
脉冲电合成有效地将芳香族有机硼试剂转化为芳基自由基。机理研究表明,脉冲电合成克服了自由基接枝/钝化、自偶联、过度氧化和分解等挑战。这种电氧化方法能够直接官能化芳香族有机硼试剂,形成芳基 C−P、C−Se、C−Te 和 C−S 键。
