 Abstract: (tmeda)Ni(acac)2 reacts with the main group metal compounds (tmeda)Mg-(CH3)2, (tmeda){Al(CH3)3}2, and (C2H5O)Al(CH3)2 at 0°C to give (tmeda)Ni-(CH3)2 (1), which can be isolated as fine yellow crystals in 50–80% yield. Complex 1, which is the simplest dialkyl nickel(II) compound with a “hard” donor ligand, is surprisingly stable and decomposes only at 79°C. 1 is converted by bipy to (bipy)Ni(CH3)2 and by Me2PC2H4PMe2 to (Me2PC2H4PMe2)Ni(CH3)2. Upon reaction of 1 with strong π-acceptor molecules (acrylic acid methylester, methyl vinyl ketone, acrylonitrile, tetracyanoethene, tetrafluoroethene, maleic anhydride) reductive elimination of the methyl groups takes place to give the complexes (tmeda)Ni(π-ligand)n (n = 1, 2) and ethane.
