Ball‐Milling‐Enabled Reactivity of Manganese Metal** [PDF]
Angewandte Chemie, 2021 AbstractEfforts 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 ...
