Terminal uranium nitrides have so far proven impossible to isolate by photolysis of azides. Here we report the second ever example of an isolated terminal uranium(VI) nitride. We show that the terminal nitride [NBu][U(OSi(OBu))(N)], , can be prepared upon photolysis with UV light of the U(IV) azide analogue. This is achieved by careful tailoring of the azide precursor and of the reaction conditions. Complex is stable under ambient conditions but reacts readily with electrophiles (H and CO).
迄今为止，通过叠氮化物的光解来分离末端氮化铀已被证明是不可能的。在此，我们报告了第二个被分离出来的末端铀（VI）氮化物实例。我们表明，末端氮化物[NBu][U(OSi(OBu))(N)]，可以通过用紫外光对U(IV)叠氮类似物进行光解来制备。这是通过精心设计叠氮前体和反应条件来实现的。配合物在环境条件下稳定，但能与亲电试剂（H和CO）迅速反应。
