molybdenum oxo-imido complex, [Mo(O)(NtBu)Cl2(dme)] (1), was obtained from the reaction between [MoO2Cl2(dme)] and [Mo(NtBu)2Cl2(dme)]. Reactions between [Mo(O)(NR)Cl2(dme)] (where R = tBu or 2,6-iPr2C6H3) and the disodium Schiff base compounds Na(2)(3,5-tBu2)2salen, Na(2)(3,5-tBu2)2salpen, and Na(2)(7-Me)2salen afforded the first oxo-imido transition metal Schiff base complexes: [Mo(O)(NtBu)[(3,5-tBu2)2salen]]
[Mo(O)(NtBu)Cl 2(dme)]与[Mo(NtBu)2 Cl 2(dme)]之间的反应获得了羰基钼-钼(1)。[Mo(O)(NR)Cl2(dme)](其中R = tBu或2,6-iPr2C6H3)与席夫碱二钠盐Na(2)(3,5-tBu2)2salen,Na(2)之间的反应(3,5-tBu2)2沙仑和Na(2)(7-Me)2salen提供了第一个羰基-亚氨基过渡金属席夫碱配合物:[Mo(O)(NtBu)[(3,5-tBu2)2salen] ](2),[Mo(O)(NtBu)[(3,5-tBu2)2salpen]](3)和[Mo(O)(N-2,6-iPr2C6H3)[(7-Me)2salen ]](4)分别。[Mo(NtBu)2(NHtBu)2]和[Mo(N-2,6-iPr2C6H3)(2)[还报道了[Mo(N-2,6-iPr2C6H3)(2)(NHtBu)2](7)的(7-Me
