Procedure

n-Dodecylamine hydrochloride (44.4 g, 0.2 mol) and phosphorus oxychloride (91.4 mL, 1.0 mol) were reacted under nitrogen. A clear solution formed within 30 minutes, and the evolution of hydrogen chloride was observed. Heating at reflux was continued for 5 hours. Excess phosphorus oxychloride was removed by distillation in vacuum (40 to 5 torr, 24° to 50° C.) forming N-(n-dodecyl)phosphoramidic dichloride as a viscous liquid. The following spectroscopic data were obtained from the liquid:
