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。报道了通过球磨进行锰介导的亚芳基丙二酸酯的还原二聚化。该过程已得到优化,并通过 CV 测量、自由基捕获和 EPR 光谱探索了其机制。对照实验表明,为了实现锰的有效活化,需要球磨而不是研钵和杵的作用,然后可以将其用于溶液或球磨机中进行后续反应。
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. A manganese‐mediated reductive dimerization of arylidene malonates by ball milling is reported. The process has been optimised and its mechanism explored by CV measurements, radical trapping, and EPR spectroscopy. Control experiments identify the action of ball milling rather than mortar and pestle is necessary to realise the effective activation of manganese, which can then be used in either solution or a ball mill for subsequent reactions.
