| Hazard Information | Back Directory | [Chemical Properties]
Diethyl cyanophosphonate is a clear colourless to yellow liquid. It soluble in most common organic solvents , such as dimethylformamide , tetrahydrofuran , diethyl ether , and toluene. Diethyl cyanophosphonate is highly toxic and corrosive. lt must be handled in awell-ventilated fume hood. In addition, it is moisture sensitive and should bestored in a refrigerator under nitrogen. | [Uses]
Diethyl cyanophosphonate was used in the synthesis of 4-acylthiol-4-deoxy-4′-demethyl epipodophyllotoxin analogs. Coupling reagent for peptide synthesis. Reagent for the phosphorylation of phenols. Activating agent for fluorescent derivatization of carboxylic acids which allows separation by HPLC. | [Application]
1973 Harusawa et al. found that diethyl phosphorocyanidate (diethyl cyanophosphonate; depc), a cyano and diethyl analog of DPPA, was a valuable reagent for peptide synthesis. DEPC is a practical and versatile reagent for organic synthesis, particularly as a condensing reagent for the synthesis of amides and peptides and its application in O-, S-, and C-acylations. Compared to other cyanating agents, DEPC is significantly less toxic and commercially available. DEPC can also be employed as a cyanating agent for introducing a C1 unit into a range of compounds, and its reaction with carbonyl compounds in the presence of a catalyst easily affords CPs, which are key intermediates in a variety of reactions[1]. | [General Description]
Diethyl cyanophosphonate (DCNP, a Tabun mimic, DECP) is a nerve agent simulant. Its detection by using fluorescein, a reversible fluorescent sensor, has been reported. Its degradation in the presence of suitable organocatalysts (different amines, aminoalcohols and glycols) has been studied. | [References]
