Reactions of endo hydride olefin complexes Cp2M(H)L (M = Ta, Nb; L = C3H6, C4H8) with C8H8 give the tantalocene and niobocene alkyls Cp2MR · C8H8. In solution these complexes partly dissociate giving free cyclooctatetraene and only endo hydride olefin complexes. Temperature-dependent 1H NMR measurements indicate that the C8H8 ligand is fluxional on the NMR time scale.
的反应内切氢化烯烃络合物的Cp 2 M(2H)L(M =钽,铌,L = C 3 H ^ 6,C 4 H ^ 8)使用C 8 ħ 8得到tantalocene和niobocene烷基的Cp 2 MR·C 8 ħ 8。在溶液中,这些配合物部分解离,得到游离的环辛酸酯和仅氢化内烯烃复合物。温度相关的1 H NMR测量结果表明C 8 H 8配体在NMR时标上是不固定的。
