The invention concerns a method for the generation of phosphorus trifluoride or a a mixture of a hexafluorophosphate and a phosphorus trifluoride or a hexafluorophosphate, a phosphorus trihalogenide, wherein the phosphorus trihalogenide is a phosphorus trichloride, a phosphorus tribromide or a phosphorus triiodide, phosphoric acid, a mixture of a tertiary phosphite ester and a phosphoric acid triester, or a tertiary aminophosphine, wherein the method comprises the following steps: a) providing an elemental phosphorus, a solvent, an oxidant having a pi-conjugated system and at least two and at most eight electron-withdrawing groups selected from chlorine, bromine, cyano and oxo, and either a fluoride anion, a chloride anion, a bromide anion, a iodide anion, water, a compound R1-OH, or a compound R2-NX1-R3, b) mixing the elemental phosphorus, the oxidant, and either the fluoride anion, the chloride anion, the bromide anion, the iodide anion, the water, the compound R1-OH or the compound R2-NX1-R3 in the solvent and c) adjusting a mixture obtained in step b) to a temperature in the range of 20 °C to 95 °C and maintaining the temperature.

Abstract
The invention concerns a method for the generation of phosphorus trifluoride or a a mixture of a hexafluorophosphate and a phosphorus trifluoride or a hexafluorophosphate, a phosphorus trihalogenide, wherein the phosphorus trihalogenide is a phosphorus trichloride, a phosphorus tribromide or a phosphorus triiodide, phosphoric acid, a mixture of a tertiary phosphite ester and a phosphoric acid triester, or a tertiary aminophosphine, wherein the method comprises the following steps: a) providing an elemental phosphorus, a solvent, an oxidant having a pi-conjugated system and at least two and at most eight electron-withdrawing groups selected from chlorine, bromine, cyano and oxo, and either a fluoride anion, a chloride anion, a bromide anion, a iodide anion, water, a compound R1-OH, or a compound R2-NX1-R3, b) mixing the elemental phosphorus, the oxidant, and either the fluoride anion, the chloride anion, the bromide anion, the iodide anion, the water, the compound R1-OH or the compound R2-NX1-R3 in the solvent and c) adjusting a mixture obtained in step b) to a temperature in the range of 20 °C to 95 °C and maintaining the temperature.File | Dimensione | Formato | |
