  Carbosilane dendrimers containing peripheral cyclopentadienyl niobium- and tantalum-imido complexes

  摘要：

  Anilines Gn-{(C6H4)N(SiMe3)(2)}(m), based on simple or dendritic carbosilanes, have been used to synthesized (imido)tantalum compounds Gn-{(C6H4)NTaCl2Cp*}(m), (1, n = 0, m = 1; 2, n = 1, m = 4; Cp* = eta(5)-C5Me5), by the reaction with [TaCl4Cp] and elimination of SiMe3Cl. (Imido)niobocene compounds of general formula Gn-{(C6H4)NNbClCp'(2)}(m) (3-5; n = 0, 1,2; m = 1,4,8, respectively) have 2 been readily prepared from their corresponding half-sandwich complexes Gn(.)(C6H4)NNbCl2Cp'}(m) by the reaction with m equiv. of LiCp'(Cp' = eta(5)-C5H4SiMe3). Compounds 1-5 are all found to be exceedingly moisture sensitive, and in the case of the (imido)niobocene materials the hydrolytic reaction selectively leads to the formation of [NbCl(O)Cp'2] (6). The molecular structure of 6 has been determined mined by X-ray diffraction studies. (c) 2006 Elsevier B.V. All rights reserved.
