A new series of N–PSe resonance-based fluorescent molecules were developed and used for the detection of hypochlorousacid (HClO) with rapid response and high selectivity. These Se-containing molecules can selectively detect trace amounts of HClO in nM, showing significantly strengthened fluorescence due to the enhanced resonance variation with an increased distance between the fluorophore and Se.

Tertiaryphosphines(III) find widespread use in many aspects of synthetic organic chemistry. Herein, we developed a facile and novel electrochemical oxidative N–H/P–H cross-coupling method, leading to a series of expected tertiaryphosphines(III) under mild conditions with excellent yields. It is worth noting that this electrochemical protocol features very good reaction selectivity, where only a 1 : 1
叔膦( III )在合成有机化学的许多方面都有广泛的用途。在此,我们开发了一种简便且新颖的电化学氧化N-H/P-H交叉偶联方法,在温和的条件下以优异的产率产生了一系列预期的叔膦( III )。值得注意的是,该电化学方案具有非常好的反应选择性,反应中仅需要胺和磷化氢的比例为1:1。此外,该电化学协议被证明是实用且可扩展的。机理分析表明 P 自由基参与了该反应。
