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.
