摘要：

Nb(eta-5-C5H4SiMe3)2X(eta-2(C,N)-R1R2CCNR3 (X = Cl, Br) species react with 1 equiv of HBF4.OEt2 to yield in one step the ionic iminoacyl complexes {Nb(eta-5-C5H4SiMe3)2X(eta-2(C,N)-R1R2HCCNR3}+BF4-. The electrochemical and the chemical reductions (Na/Hg) of these cationic complexes give the starting ketenimine complexes with the elimination of H-2. The molecular structure of {Nb(eta-5-C5H4SiMe3)2X(eta-2(C,N)-EtPhHCCNPh}+BF4- shows an eta-2(C,N)-bonded iminoacyl ligand.
