The alkenyl substituted fulvene compound,(C5H4) CMe (CH2CH2CHCMe2)(1), reacts with one equivalent of LiMe to give the lithium derivative Li {C5H4 (CMe2CH2CH2CHCMe2)}(2). The reaction of 2 with Me2Si (C5Me4H) Cl gave the ansa-ligand precursor Me2Si (C5Me4H)(C5H4 (CMe2CH2CH2CHCMe2))(3), which after the subsequent reaction with 2 equivalents of LiBun yielded the dilithium salt Li2 {Me2Si (C5Me4)(C5H3 ( ...
