Abstract

The reactions of N~2~O~2~‐donor‐type aminopodands 1–3 with trimer N~3~P~3~Cl~6~ led to the novel spirocyclic phosphazene derivatives 4–10 (Scheme). Compounds 4–7 and 8–10 are the first examples of the substituted spiro‐ansa‐spiro and spiro‐bino‐spiro phosphazene derivatives, respectively. The pyrrolidinyl‐substituted phosphazene derivatives 7 and 10 were synthesized from 5 and 9, respectively, with an excess of pyrrolidine. The reaction of aminopodand 3 (R(CH~2~)~4~) with N~3~P~3~Cl~6~ in dry THF afforded only spiro‐ansa‐spiro phosphazene 6. The molecular structure of compound 9 was determined by X‐ray diffraction: it shows the novel spiro‐bino‐spiro phosphazene architecture.
