The first isolable pentacoordinate 1,2 lambda 5-azaphosphetine: synthesis, X-ray crystallographic analysis, and dynamic behaviour.
Cycloaddition reaction of an iminophosphorane bearing the Martin ligand with an alkyne gave the first stable 1,2 lambda 5-azaphosphetine, whose structure was determined by X-ray crystallographic analysis, and variable temperature NMR spectroscopy revealed the existence of equilibrium with the corresponding alpha-iminoalkylidenephosphorane.
