| الوصف: | A range of potential boron-based ligand precursors has been synthesized starting from [{Br2B(η5-C5H4)}Mn(CO)3] (1) via salt elimination reactions. These comprise ligand precursors suitable for the preparation of i) ansa-metallocenes such as [CymB(η1-C5H5)2] (2), [CymB(1-C9H7)2] (3a), and [CymB(3-C9H7)2] (3b), ii) constrained geometry complexes such as [CymB(Br)N(H)tBu] (5) as well as iii) ansa-diamido complexes such as [CymB{N(H)Ph}2] (4) and [CymB{N(H)tBu}2] (6) (Cym = cymantrenyl, C5H5 = cyclopentadienyl, C9H7 = indenyl). Furthermore, we present the hydrolysis of 1, leading to the three-fold cymantrenyl-substituted boroxine [{OB(η5-C5H4)}Mn(CO)3]3 (7). All new compounds have been characterized by multinuclear NMR spectroscopic techniques and in the case of 1 and 7 by X-ray diffraction analyses. |
