摘要

The ligands ferrocenyltris((methylthio)methyl)borate (FcTt− ) and phenyltris-((t-butylthio)methyl)borate ( PhTttBu- ) have been synthesized and characterized. Each ligand has been demonstrated to be a good ligand for first row transition metal complexes. FcTt − forms octahedral complexes of the form [FcTt]2M with divalent first row transition metal ions. These complexes have been characterized and compared to their phenyltris((methylthio)methyl)borate (PhTt− ) counterparts. The data demonstrate that the electronic properties of Ni(II), Fe(II) and Co(II) complexed by the FcTt− ligand are similar to the same metal ions complexed by the PhTt− ligand. FcTt− also reacts with [Cu(I)(CH3CN) 4]BF4 to form a tetrameric structure similar in nature to [PhTtCu]4. Further reactivity studies with the [FcTt]2M complexes were hampered by their coordinative saturation.; The sterically hindered ligand PhTttBu- , in contrast to the less hindered FcTt− and PhTt − ligands, forms tetrahedral metal complexes, LMX, with first row divalent transition metal halides. This demonstrated the ability of this ligand to prevent formation of L2M complexes due to the added steric bulk of the t-butyl moieties. While this ligand does prevent the binding of a second borate ligand it does not preclude the formation of complexes with higher coordination numbers. PhTttBu- has been used to prepare four, five, and six coordinate complexes with divalent first row transition metal ions. Complexes of the form [ PhTttBu- ]MX, where X is a halide or nitrate ion, have proven to be useful starting materials for the preparation of a variety of coordination complexes with Ni(II) and CO(II). These include a Co-CH3 species that undergoes CO insertion and an intriguing Ni(II) organometallic species formed via boron-carbon bond cleavage in the presence of an excess of the borate ligand.
