  Electrochemical and chemical reduction of niobocene dichlorides in the presence of carbon dioxide

  摘要：

  The chemical and electrochemical reduction of the niobocene dichlorides [Nb(eta(5)-C(5)H(4)SiMe(3))(2)Cl-2] 1, [Nb(eta(5)-C(5)Me(5))(2)Cl-2] 2 and [Nb(eta(5)-C(5)Me(4)Et)(2)Cl-2] 3, in the presence of carbon dioxide has been investigated. Formation of compounds of the type [Cp(2)Nb(CO2)] and [Cp(2)((*))NbCl(CO2)](1) has been established by means of IR, ESR and/or NMR spectroscopy. They contain a labile eta(2)-CO2. The order of stability increases with the degree of substitution the Cp. Less stable intermediates in the reduction of the system [Cp(2)NbCl(2)]/CO2 are discussed on the basis of cyclovoltammetric and coulometric data.
