Abstract

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 where upon pre-milling of the manganese is required.
