摘要：

A new stepwise preparation of tungstenocene derivatives [Cp(2)WL(2)][BF4](2) (L=CO or NCMe) from [W(CO)(6)] via [CpW(eta(3)-C-3- H-5)(CO)(2)] and [CPW(eta(4)-C5H6)(CO)(2)]BF4 is described. Similar preparations, starting from [(eta(5)-C9H7)W(eta(3)-C3H5)(CO)(2)], lead to the first mixed-ring indenyl analogues of tungstenocene, [IndCpWL(2)][BF4](2) (L = CO or NCMe) and [CpW(eta(3)-Ind)(CO)(2)]. Reversible ring slippage between [(eta(5)-C9H7)W(CO)(2)(NCMe)(2)]BF4 and [(eta(3)-C9H7)W(CO)(2)(NCMe)(3)]BF4 is observed.
