[U(NR 2)3](R = SiMe 3)与2当量的2,6-二甲基苯基异氰化物的反应导致以50%产率分离U(III)双(异氰化物)络合物[U(NR 2)3(CN Xyl)2](1)。在1中加入1当量[Cp*2Co],生成异氰脲酸偶联的U(IV)配合物[Cp*2Co][{η2-C,N-(Xyl)NCCN(Xyl)}U(NR 2)3](2),经后处理后,可将其分离,产率为45%。配合物2的结构经核磁共振谱和X-射线晶体学表征。在固态下,它的炔二酰胺配体以η2-N,C键合模式存在。
The reaction of [U(NR2)3] (R = SiMe3) with 2 equiv of 2,6-dimethylphenyl isocyanide results in the isolation of the U(III) bis(isocyanide) complex [U(NR2)3(CNXyl)2] (1) in 50% yield. Addition of 1 equiv of [Cp*2Co] to1results in formation of the isocyanide-coupled U(IV) complex [Cp*2Co][{η2-C,N-(Xyl)NCCN(Xyl)}U(NR2)3] (2), which can be isolated in 45% yield after workup. Complex2was characterized by NMR spectroscopy and X-ray crystallography. In the solid state, its acetylenediamide ligand features an η2-N,Cbinding mode.
