Abstract

Azidophosphanes are versatile reactants in the Staudinger reaction. The azides Cl2PN3 (1), (Et2N)ClPN3 (2), and (Et2N)2PN3 (3) react with phosphanes to give the N-phosphanyl phosphazenes 4–10. (Et2N)P(N3)2 is oxidized by PhN3 yielding (Et2N)P(N3)2NPh (11), which with PPh3 yields the di- and triphosphazenes 12 and 13.
