Abstract

Three NNOPP [R-C₅H₃N-C₅H₃N-COH-(C₆H₄-PPh₂)₂, L₁: R = OCH₃, L₂: R = H, L₃: R = CF₃] ligands are synthesized and introduced to cobalt centers. The corresponding dicobalt complexes[{R-C₅H₃N-C₅H₃N-COH-(C₆H₄-PPh₂)₂}Co₂Cl₃ (1: R = OCH₃, 2: R = H, 3: R = CF₃)], which are bench-stable, are developed, respectively. The regioselective hydrosilylations of terminal alkynes with primary silane are investigated to produce (E)-vinylsilanes in good yields with excellent regioselectivity, and complex 3 exhibits the highest activity.

利用二钴配合物将炔氢硅高效和区域选择性地水解为(E)-β-乙烯基硅烷

合成了3种NNOPP [R- c5h3n - c5h3n - coh -(C6H4-PPh2)2, L1: R = OCH3, L2: R = H, L3: R = CF3]配体并引入钴中心。相应的二钴配合物[{R- c5h3n - c5h3n - coh -(C6H4-PPh2)2}Co2Cl3 (1: R = OCH3, 2: R = H, 3: R = CF3)]分别具有台架稳定性。研究了末端炔与伯硅烷的区域选择性硅氢化反应，得到了收率高、区域选择性好的(E)-乙烯基硅烷，其中配合物3活性最高。

期刊介绍： All new compounds should be satisfactorily identified and proof of their structure given according to generally accepted standards. Structural reports, such as papers exclusively dealing with synthesis and characterization, analytical techniques, or X-ray diffraction studies of metal-organic or organometallic compounds will not be considered. The editors reserve the right to refuse without peer review any manuscript that does not comply with the aims and scope of the journal. Applied Organometallic Chemistry publishes Full Papers, Reviews, Mini Reviews and Communications of scientific research in all areas of organometallic and metal-organic chemistry involving main group metals, transition metals, lanthanides and actinides. All contributions should contain an explicit application of novel compounds, for instance in materials science, nano science, catalysis, chemical vapour deposition, metal-mediated organic synthesis, polymers, bio-organometallics, metallo-therapy, metallo-diagnostics and medicine. Reviews of books covering aspects of the fields of focus are also published.
