The preparation of various N-(aminophenyl)iminophosphoranes is described.The new compounds are characterized by the usual analytical methods and by 31P-NMR spectroscopy.For some compounds the results indicate an equilibrium with 2,3-dihydro-1,3,2-λ5-benzdiazaphospholes.The equilibrium constants and the thermodynamic parameters ΔH, ΔG and ΔS are obtained by quantitative NMR measurements.The position of the equilibrium depends strongly on the subsituents as weel as on the solvent used.
