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 rearrangementoccurs 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.
