The first mixed phosphatetrahedranes were reported only recently and their reactivity is virtually unexplored. Herein, we present a reactivity study on di-tert-butyldiphosphatetrahedrane (1), which is the dimer of tert-butylphosphaalkyne. The (tBuCP) tetrahedron is activated selectively by N-heterocyclic carbene (NHC) nickel(I) and nickel(0) complexes, resulting in novel complexes featuring diverse (tBuCP) -frameworks (n=2, 4). Release of the (tBuCP) framework from one of the complexes was achieved by addition of CO gas. Furthermore, 1 can be used as a source for P units by elimination of di-tert-butylacetylene in the coordination sphere of nickel.
首例混合磷四面体烷直到最近才被报道，其反应活性几乎尚未被探索。在此，我们展示了对二叔丁基二磷四面体烷（1）的反应活性研究，它是叔丁基磷炔的二聚体。（tBuCP）四面体通过氮杂环卡宾（NHC）镍（I）和镍（0）配合物被选择性活化，生成具有不同（tBuCP）骨架（n = 2, 4）的新型配合物。通过添加CO气体实现了从其中一种配合物中释放（tBuCP）骨架。此外，在镍的配位球中通过消除二叔丁基乙炔，1可以用作P单元的来源。
