在球磨条件下生成有机锰试剂的努力导致了偶然的发现，即金属锰可以介导亚芳基丙二酸酯的还原二聚。新发现的过程已得到优化，并利用 CV 测量、自由基捕获实验、EPR 光谱和溶液控制反应探索其机制。这种独特的反应性也可以转化为需要预研磨锰的溶液。
Efforts to generate organomanganese reagents under ball‐milling conditions have led to the serendipitous discovery that manganese metal can mediate the reductive dimerization of arylidene malonates. The newly uncovered process has been optimized and its mechanism explored using CV measurements, radical trapping experiments, EPR spectroscopy, and solution control reactions. This unique reactivity can also be translated to solution whereupon pre‐milling of the manganese is required.
