Individual Reactions

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

By formula: F- + F2S2 = (F- bullet F2S2)

Deltar151. ± 13.kJ/molIMRBLarson and McMahon, 1987gas 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
