Hexaethyl phosphorous triamide, 97%, Thermo Scientific Chemicals
Hexaethyl phosphorous triamide is used in the Barton syntheses of hindered alkenes, involving desulfurization of small-ring heterocycles with elimination of nitrogen or carbon dioxide. It is also used as a reagent for selective vicinal dehalogenation of halogenated alkanes to give perhalogenated alkenes. The method has potential for the synthesis of highly fluorinated and mixed fluoro-halo alkenes.
This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
