Two uranium(III) anilido complexes were synthesized, TpU(NH-CH--terpyridine) () and TpU(NH-CH--CH) (), where Tp* = hydrotris(3,5-dimethylpyrazolyl)borate, by protonation of TpUBn (; Bn = benzyl) with 4-[2,6-di(pyridin-2-yl)pyridin-4-yl]benzenamine or -toluidine, respectively. Conversion to the respective uranium(IV) imido species was possible by oxidation and deprotonation, forming TpU(N-CH--terpyridine) () and Tp*U(N-CH--CH) (). These compounds were characterized by multinuclear NMR spectroscopy, IR spectroscopy, electronic absorption spectroscopy, and X-ray crystallography.
合成了两种铀（III）苯胺基配合物，即TpU(NH-CH--三联吡啶)（）和TpU(NH-CH--CH)（），其中Tp* = 氢三（3,5-二甲基吡唑基）硼酸酯，分别通过用4-[2,6-二（吡啶-2-基）吡啶-4-基]苯胺或对甲苯胺使TpUBn（；Bn = 苄基）质子化得到。通过氧化和去质子化可以将其转化为相应的铀（IV）亚氨基物种，形成TpU(N-CH--三联吡啶)（）和Tp*U(N-CH--CH)（）。这些化合物通过多核核磁共振光谱、红外光谱、电子吸收光谱和X射线晶体学进行了表征。
