Using the Staudinger reaction, we have synthesized twelve iminophospholanes (1-12) with dioxa (1-4), oxaza (5,6), and diaza (7-12) ring systems.We have never observed any phosphazene bond dimerization with diazaphospholane compounds, whatever the nature of the group on the imino atom.For the tetramethyl dioxaphospholane compounds (1,2,4), the thermal rearrangement occurs with the intracyclic oxygen atom.Last of all, the reactivity of the phosphazene bond with methanol differs according to the nature of the ring: addition leading to the pentacoordinated species in pinacolic compounds, intermolecular associations (hydrogen bonding) in diazaphospholane derivatives.

The tris(amino)-iminophosphanes (1 to 5) react under mild conditions with acetylenic esters (a, b, c).Five new phosphorus ylides (1a to 3c) with β carbonyl group have been obtained.The chemical behavior (unreactivity with methanol and acetone) and 13C NMR study suggest that the phenyl imino group is involved in the delocalization of the carbanionic negative charge.
