Two silylene nickel carbonyl complexes of composition L·Ni(CO)(3) (1) {L = PhC(NtBu)(2)SiCl} and L'(2)·Ni(CO)(2) (2) { L' = RSiCl(2), R = (1,3-bis-(2,6-diisopropylphenyl)imidazol-2-ylidene)} were prepared by reacting 1 equivalent of Ni(CO)(4) with 1 equivalent of heteroleptic chlorosilylene L for 1 and with 2 equivalents of carbene stabilized dichlorosilylene L' for 2 in toluene at room temperature. Both complexes 1 and 2 were characterized by single-crystal X-ray analysis, NMR and IR spectroscopy, EI-MS spectrometry, and elemental analysis.
两种组成式为 L·Ni(CO)(3)（1）{L = PhC(NtBu)(2)SiCl}和 L'(2)·Ni(CO)(2)（2）{ L' = RSiCl(2), R = (1,3-双-(2,6-二异丙基苯基)咪唑-2-亚基)}的二硅亚基镍羰基配合物是通过在室温下将 1 当量的 Ni(CO)(4)与 1 当量的杂配氯代硅烷 L 反应 1 小时，与 2 当量的卡宾稳定二氯代硅烷 L'反应 2 小时来制备的。配合物 1 和 2 均通过单晶 X 射线分析、NMR 和 IR 光谱、EI-MS 光谱和元素分析进行了表征。
