✦ Synopsis

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