通过Tp*2UBn （1-Bn; Bn =苄基）与4-[2,6-二（吡啶-2-基）吡啶-4-基]苯胺或对甲苯胺的质子化反应，合成了两个铀（III）苯胺配合物Tp*2U（nh - c6h4 -对三吡啶）（2-terpy）和Tp*2U(nh - c6h4 -对- ch3)（2-苯基）。通过氧化和去质子化反应，分别生成Tp*2U(N-C6H4-p-terpyridine) （3-terpy）和Tp*2U(N-C6H4-p-CH3) （3-ptol）。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。
Two uranium(III) anilido complexes were synthesized, Tp*2U(NH-C6H4-p-terpyridine) (2-terpy) and Tp*2U(NH-C6H4-p-CH3) (2-ptol), where Tp* = hydrotris(3,5-dimethylpyrazolyl)borate, by protonation of Tp*2UBn (1-Bn; Bn = benzyl) with 4-[2,6-di(pyridin-2-yl)pyridin-4-yl]benzenamine orp-toluidine, respectively. Conversion to the respective uranium(IV) imido species was possible by oxidation and deprotonation, forming Tp*2U(N-C6H4-p-terpyridine) (3-terpy) and Tp*2U(N-C6H4-p-CH3) (3-ptol). These compounds were characterized by multinuclear NMR spectroscopy, IR spectroscopy, electronic absorption spectroscopy, and X-ray crystallography.
