Reactions de tris(alcoxy)iminophosphanes avec l'acetylene dicarboxylate de methyle: ylure, phosphonate et phosphorane

The tris(alkoxy) N-phenyl iminophosphanes react under mild conditions with acetylenic carboxylates to give phosphorus ylides with a β carbonyl group.These compounds, well characterized in the reaction mixture, have not been isolated.They are highly reactive and depending on the nature of substituents on phosphorus atom; give phosphonates, phosphoranes and cyclic ylides.

ARYLIMINO DERIVATIVES OF METHYL-1,3,2λ5-DIOXAPHOSPHOLANES. SYNTHESIS AND DIMERIZATION

The tendency of 2-alkoxy-2-(arylimino)-1,3,2λ5-dioxaphospholanes to dimerize with the formation of the corresponding diazadiphosphetidines falls substantially on the introduction of acceptor substituents on the imino nitrogen and of four methyl groups into the heterocycle, which lower the inductive acceptor power of the cyclic substituent and shield the phosphorus atom.

La liaison phosphazene dans quelques nouveaux iminophospholanes. Diversite de comportement reactionnel

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.
