摘要：

Reactions of monocyclopentadienyl complexes M(eta-5-CP')Cl4 with trimethylsilylmethyl lithium leads to the formation of alkylidene derivatives M(eta-5-CP')(CH2SiMe3)2(CHSiMe3), where M = Nb (1); Ta (2); Cp'= C5Me5 and M = Ta; Cp'= Me3Si(C5H4) (3), 1,3-(Me3Si)2(C5H3) (4). The new complexes were characterized by H-1 and C-13 NMR spectroscopy and the molecular structure of 2 was studied by X-ray diffraction methods.
