Abstract

Treatment of [Mo(N2)(PMe3)5] with two equivalents GaCp* (Cp* = η5-C5(CH3)5) leads to the formation of cis-[Mo(GaCp*)2(PMe3)4] (1), while AlCp* did not react with this precursor. In addition, [Ni(GaCp*)2(PPh3)2] (2a), [Ni(AlCp*)2(PPh3)2] (2b), [Ni(GaCp*)2(PCy3)2] (3a), [Ni(GaCp*)2(PMe3)2] (3b), [Ni(GaCp*)3(PCy3)] (4) and [Ni(GaCp*)(PMe3)3] (5) have been prepared in high yields by a direct synthesis from [Ni(COD)2] and stoichiometric amounts of the ligands PR3 and ECp* (E = Al, Ga), respectively. All compounds have been fully characterized by 1H, 13C, and 31P NMR spectroscopy, elemental analysis and single crystal X-ray diffraction studies.
