[(dmpe)2MnH(C2H4)] as a Source of a Low-Coordinate Ethyl Manganese(I) Species: Reactions with Primary Silanes, H2, and Isonitriles

Wilkinson’s manganese­(I) ethylene hydride complex trans-[(dmpe)2MnH­(C2H4)] (1) reacts as a source of a low-coordinate manganese­(I) ethyl complex. This is illustrated in the reactivity of 1 toward a variety of reagents. Reactions of 1 with primary silanes RSiH3 (R = Ph, n Bu) at 60 °C afforded ethane and the disilyl hydride manganese complexes [(dmpe)2MnH­(SiH2R)2] (4a, R = Ph; 4b, R = n Bu). Additionally, reaction with H2 at 60 °C afforded …
