Reaction Conditions

Reaction Steps

Methyl bis(pentafluoroethyl)phosphinate, (C2F5)2P(O)OCH3, (2.755 g; 8.7 mmol) is added at room temperature to triphenyl phosphite, P(OC6H5)3, (2.075 g; 6.7 mmol) in a 10 ml glass flask. The two-phase reaction mixture is warmed and stirred at 60° C. for 5.5 h. A cloudy and colourless reaction mixture forms, that is stirred at RT for 16 h and at 60° C. for 5 h. Methyl bis(pentafluoroethyl)phosphinate, (C2F5)2P(O)OCH3, (0.380 g; 1.2 mmol) is added again, and the mixture is again stirred at 60° C. for 5.5 h. Methyltriphenoxyphosphonium bis(pentafluoroethyl)phosphinate, [(C6H5O)3PCH3]-[(C2F5)2P(O)O], can be isolated as white and crystalline solid (3.827 g; 6.1 mmol) in a yield of 91% and a purity of 89% by purification in vacuo (10−3 mbar) at 80° C.
