ABSTRACT
The aim of this review is to provide a comprehensive view of the chemistry of cationic polyphosphorus cages. The synthetic protocols established for their preparation, which are all based on the functionalization of P4, and their intriguing follow-up chemistry are highlighted. In addition, this review intends to foster the interest of the inorganic, organic, catalytic and material oriented chemical communities in the versatile field of polyphosphorus cage compounds. In the long term, this is envisioned to contribute to the development of new synthetic procedures for the functionalization of P4 and its transformation into (organo-)phosphorus compounds and materials of added value.

Mentions: A phosphenium ion bearing only alkyl- or aryl-substituents has not been isolated to date.18 The reaction of phosphanes bearing organo- and chloro-groups RnPCl(3–n) (n = 1, 2) and a halide abstracting agent (e.g. Me3SiOTf, GaCl3, or AlCl3) in the appropriate stoichiometry usually results in the formation of phosphanylphosphonium ions.1 This is best exemplified by the reaction of Ph2PCl and GaCl3 in a 2 : 1 stoichiometry which yields 8[GaCl4] (Scheme 1).22
