Fluoridolyse von N-Phosphorylphosphazenen

Fluoridolysis of N-Phosphoryl Phosphazenes In the reaction of the N-phosphoryl phosphazenes X₃P?N? P(Y)X₂ (X = Cl, PhO, Et₂N, CF₃CH₂O, PrS, Ph; Y = O, S) ( 1 – 18 ) with Et₃N · nHF (n ≈? 3 or 0.6) fluoro derivatives of N-phosphoryl phosphazenes (see table 2) as well as N-phosphorylated imiddotetrafluorophosphates, F₄P?N? P(Y)Cl₂]^? (Y = O, S), and imidopentafluorophosphates, F₅P? N? P(Y)X₂]^2? or F₅P? NH? P(O)X₂]^? (see table 3), are formed. t-BuNHPCl₂?N? POCl₂ reacts in acetonitrile with Et₃N or i-Pr₂EtN to form a product, representing probably the diazadiphosphetine ( 5 b ).
