| Bis(dimethyIphosphino)methan-Nickel(0)-Komplexe Bis(dimethylphosphino)methane-Nickel(0) Complexes  | | | | Abstract
| The reaction of tris(ethene)nickel(0) with stoichiometric amounts of bis(dimethylphos-phino)methane (dmpm) in ether at low temperature affords the yellow crystalline, dinuclear complexes (dmpm)Ni 2 (QH 4) 4 (1) and (dmpm)2Ni 2 (C 2 H 4)2 (2). 2 reacts with ethyne to yield (dmpm) 2 Ni 2 (C 2 H 2) 2 (3). When 2 is treated with CO at —40 °C the primary product is (dmpm) 2 Ni 2 (CÖ) 2 (w-CO) (4). At 20 °C 4 is converted by additional CO into (dmpm) 2 Ni 2 (CO) 4 (5), which has already been characterized as the reaction product of Ni(CO) 4 with dmpm. In compounds 1—5 the bidentate dmpm acts as a bridging and not as a chelating ligand. The structures of complexes 1—4 were assigned on the basis of their 13 C and 31 P NMR spectra. | | | |
