通过NaBH4与咪唑酮的反应，合成了一类具有三个供氧体的新型L2X三足配体，即三（2-氧-1-叔丁基咪唑基）和三（2-氧-1-甲基苯并咪唑基）氢硼配体[To(But)]和[To(MeBenz)]。结构和光谱研究表明，[To(But)]和[To(MeBenz)]的空间要求明显高于[O-3]供体配体[CpCo{P(O)(OEt)(2)}(3)]，但给电子量较少。
A new class of tripodal L2X ligands that feature three oxygen donors, namely the tris(2-oxo-1-tert-butylimidazolyl) and tris(2-oxo-1-methylbenzimidazolyl) hydroborato ligands, [To(But)] and [To(MeBenz)], has been synthesized via the reactions of NaBH4 with the respective imidazolone. Structural and spectroscopic studies indicate that both [To(But)] and [To(MeBenz)] are significantly more sterically demanding but less electron donating than the related [O-3] donor ligand, [CpCo{P(O)(OEt)(2)}(3)].
