Abstract

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, [ToBut] and [ToMeBenz], has been synthesized via the reactions of NaBH4 with the respective imidazolone. Structural and spectroscopic studies indicate that both [ToBut] and [ToMeBenz] are significantly more sterically demanding but less electron donating than the related [O3] donor ligand, [CpCo{P(O)(OEt)2}3].
