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.

sch16: Reaction of α-P4S3I2 with Ag(CH2Cl2)[A], A = Al(OC(CF3)3)4.

Mentions: The second protocol is based on halide abstraction from α-P4S3I2 with Ag(CH2Cl2)[Al(OC(CF3)3)4] and yields the spiro-cyclic cage cation 58+ (Scheme 16).62 The initial step involves the formation of 57+via iodide abstraction from α-P4S3I2. Cation 57+ subsequently reacts with a second equivalent of α-P4S3I2 and this in association with the formal extrusion of phosphinidene [PI] gives rise to spiro-cyclic cage 58+. However, detailed information on the mechanism of the formation of 58+ was not gained. The structural motif of this cation is unprecedented and contains the first tetra-coordinated P atom exclusively bonded to P and S atoms.62
