Synthesis of diphenylphosphoryl azide

Preparation of diphenylphosphoryl azide

Alternative Names: Diphenyl phosphoryl azide; Diphenyl azidophosphate; Diphenylphosphonic azide; DPPA;

A mixture of 56.8 g (0.24 mole) of diphenyl chlorophosphate and 46.3 g (0.25 mole) of sodium azide in dry acetone is stirred at room temperature for 24 hours. The filtered solution is concentrated on a rotary evaporator and the obtained residue is distilled under vacuum (0.15 mmHg) at 152-155 °C. The yield of diphenylphosphoryl azide is 53.3 g (92%) as a colorless oil.
