Cp3UNEt2 also reacts with an excess of HCp to give UCp4. For the preparation of the complexes Cp2U(NR2)2 (R = Et or Ph) and Cp3UNEt2, an alternative route, starting from UCl4, TlCp and LiNEt2 (KNPh2) and from Cp3UCl and LiNEt2, respectively, has also been developed. The new complex CpU(NEt2)3 does not readily undergo ligand redistribution to give Cp2U(NEt2)2 and U(NEt2)4, but it appears to react with another
U(NEt 2)4和Th(NEt 2)4都可以用
环戊二烯进行
化学计量和动力学控制,以使各种产物CP n f M(NEt 2)4- n(n = 2,3,f M = U ;n= 1、2、3,f M = Th)可以分别以高收率获得。CP 3 UNEt 2也与过量的HCP反应生成UCP 4。用于制备配合物CP 2 U(NR 2)2(R = Et或Ph)和CP 3UNET 2,替代路线,从UCL开始4,TLCP和利内2(KNPh 2)和自CP 3 UCL和利内2分别也已经被开发。新的复合物CPU(NEt 2)3不会轻易进行
配体重新分布以产生CP 2 U(NEt 2)2和U(NEt 2)4,但是它与另一个HCP分子的反应似乎比U(NEt 2)快得多。)4。
