Shalev, D. E., Chiacchiera, S. M., Radkowsky, A. E., Kosower, E. M. Sequence of Reactant Combination Alters the Course of the Staudinger Reaction of Azides with Acyl Derivatives. Bimanes. 30. J. Org. Chem. 1996, 61, 1689-1701. 

The Staudinger reaction of azides with tertiary phosphines is one of the two major routes in the preparation of iminophosphoranes [30]. This reaction proceeds... 

Iminophosporanes (phosphazenes) are easily formed by a Staudinger reaction of azides with triphenylphosphine or a Kirsanov reaction, which is a process that takes place between an amine and dichlorotriphenylphosphorane. The ready availability of...
