摘要

On account of our interest in P-4 activation by phosphenium ion insertion into P-P bonds we have developed synthetic routes to bicyclic N-P-Si-heterocycle 7 and probed its reactivity towards GaCl3 and P-4. A GaCl3-induced rearrangement of 7 leads to the in situ formation of spirocyclic, Si-centered phosphenium ions. Their insertion into P-P bonds of one or two P-4 tetrahedra yields polyphosphorus cages [ClP(NSiMe3)(2)Si(NSiMe3)(2)P-5](+) (19(+)) and [P-5(NSiMe3)(2)Si(NSiMe3)(2)P-5](2+) (13(2+)).
