being unchanged in all the reactions described. Addition of H2NtBu to [(MCl4)2(μ-CpnCp)] (M = Mo, n = 1, 2a; n = 2, 2b; M = W, n = 2, 2c) affords the imido M(V) complexes [M(NtBu)Cl2}2(μ-CpnCp)] (4a−c). Complexes 4a,c are oxidized by PCl5 to give [M(NtBu)Cl3}2(μ-CpnCp)] (5a,c). Both 4a and 5a afford [MoCl(μ-NtBu)}2(μ-Cp1Cp)] (6) by reduction with sodium amalgam.
