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)(2) tetrahedron is activated selectively by N-heterocyclic carbene (NHC) nickel(I) and nickel(0) complexes, resulting in novel complexes featuring diverse (tBuCP)(n)-frameworks (n=2, 4). Release of the (tBuCP)(4) framework from one of the complexes was achieved by addition of CO gas. Furthermore, 1 can be used as a source for P-2 units by elimination of di-tert-butylacetylene in the coordination sphere of nickel.
