使用Diphenylphosphoryl azide (DPPA or diphenyl phosphorazidate, (PhO)2P(O)N3) is a very toxic and potentially explosive organic compound. DPPA has been found to be effective for a variety of organic reactions as a versatile synthetic reagent. It is widely used in synthesis of other organic compounds especially as a reagent for the synthesis of peptides by virtue of its reactions with carboxylic acids leading to either the urethane or the amide.
製造方法Diphenylphosphoryl azide (DPPA) is easily prepared in high yield by the reaction of the corresponding chloride with sodium azide in acetone. Combination of sodium azide and 18-crown-6 in the same reaction was reported, and the use of a quaternary ammonium salt as a phase-transfer catalyst in a biphasic phase of water and an organic solvent was also reported to be effective, as shown in Scheme 3.Diphenyl Phosphorazidate (DPPA) - More Than Three Decades LaterTakayuki ShioiriGraduate School of Environmental and Human Sciences, Meijo University

化学的特性Diphenylphosphoryl azide (DPPA) is a colorless or pale yellow liquid which boils at 134-136 °C/0.2 mmHg, and it will be stable at room temperature under shading. It is non-explosive just like the other phosphorazidate. When DPPA is stored at room temperature for a long time, it might be slowly and partially hydrolyzed with moisture in air to produce diphenyl phosphate and toxic explosive hydrazoic acid. In this case, it will be recommended to use after washing DPPA with aqueous sodium hydrogen carbonate followed by drying.
