practically useful coupling reaction between aromatic halides and redox-active esters was realized by nickel catalysis through the use of a packed zinc bed column in continuous flow. Multiple reuse of the column showed a negligible decrease in efficiency, affording high space/time yields. A wide range of substrates, including a number of heteroaryl halides and polyfunctional materials were coupled in generally
通过使用连续流动的填充锌床塔,通过镍催化实现了芳族卤化物和氧化还原活性酯之间的实用偶联反应。色谱柱的多次重复使用显示效率的降低可忽略不计,从而提供了高的空间/时间产率。包括许多杂芳基卤化物和多官能材料在内的多种底物以通常良好的产率偶联。较长时间的大规模实验进一步证明了该系统的鲁棒性。
