Individual Reactions

Fluorine anion + Phosphoryl fluoride = (Fluorine anion bullet Phosphoryl fluoride)

By formula: F- + F3OP = (F- bullet F3OP)

Quantity Value Units Method Reference Comment
Deltar200. ± 8.4kJ/molIMRELarson and McMahon, 1985gas phase; These relative affinities are ca. 10 kcal/mol weaker than threshold values (see Wenthold and Squires, 1995) for donors greater than ca. 27 kcal/mol in free energy. This discrepancy has not yet been resolved, though the stronger value appears preferable.; B,M
Deltar201. ± 38.kJ/molIMRBRhyne and Dillard, 1971gas phase; Fluoride Affinity: SF4>F3PO>SF5. Orignal value 32±10, now reval. with new affinities; B
