Reaction Conditions

Reaction Steps

2.14 g (19.3 mmol) of selenium dioxide, SeO2, are added to 12.445 g (17.1 mmol) of tris(nonafluorobutyl)difluorophosphorane, (C4F9)3PF2, in a 100 ml glass round-bottomed flask and warmed (120° C. oil-bath temperature). An intensive reflux condenser is connected downstream of the flask. The suspension is stirred at 120° C. for 3 h. After this time, no weight loss, but complete consumption of (C4F9)3PF2 and formation of (C4F9)3P═O can be detected. The entire suspension is condensed at 80° C. in vacuo (10−3 mbar). Clear and colourless (C4F9)3P═O (7.426 g; 10.5 mmol; 62%) in 87% purity can be isolated.
