Procedure

A solution of 1.16 g (3.0 mmol) of tris(pentafluoroethyl)phosphine, (C2F5)3P, in 1,2-dimethoxyethane is treated with an excess (6 mmol) of a 1.5 M solution of KOH in water. The mixture is stirred at room temperature for 30 min, and the solvent is removed in vacuo. The residue is taken up in 1,2-dimethoxyethane, and an excess of PCl5 (6 mmol) is added, giving bis(pentafluoroethyl)phosphinous acid chloride, (C2F5)2PCl, identified as described above.
