摘要：

Reaction of the binuclear alkoxide species [Nb(Cl)(3)(OR)(2)](2) (R =Me, Et) with potassium hydridotris (3,5-dimethylpyrazol-1-yl)borate, KTp*, leads to Tp*Nb(O)(Cl)(OR) (R =Me(1), Et(2)). These complexes react with Me3SiCl or PCl3 to give Tp*Nb(O)(Cl)(2) (3). The binuclear complex [{Tp*Nb(O)(Cl)}(2)(mu-O)] (4) was prepared by the controlled hydrolysis of 1 or 2. Finally, complex 3 reacts with (Me3Si)(2)NMe or LiN(SiMe3)(2). Et2O to give Tp*Nb(O)(HNSiMe3)(2) (5) as the only isolated niobium product. Compounds 4 and 5 were characterized by X-ray diffraction.
