不可复制粘贴：虽然β-双酮配体已被用于稳定Ge（II）和Sn（II）氢化物，但相应的Si（II）氢化物是不可接近的。然而，硅（II）与{Ni(CO)(3)}片段的配位使得第一个Si（II）氢化物金属配合物1得以分离。该配合物首次用于硅（II）基和Ni(0)介导的烷基立体选择性硅氢化反应。R =苯基，甲苯。
Not copy and paste: Although β-diketiminato ligands have been employed for the stabilization of Ge(II) and Sn(II) hydrides, the corresponding Si(II) hydride is not accessible. However, coordination of silicon(II) to a {Ni(CO)(3)} fragment allowed the isolation of the first Si(II) hydride metal complex 1. This complex was used for the first silicon(II)-based and Ni(0)-mediated, stereoselective hydrosilylation of alkynes. R = phenyl, tolyl.
