The reaction of bis[bis(dialkylamino)phosphanyl]methanes 1a,b with bis(trifluoromethyl)acrylonitrile 8 led to the ylides 10a,b which showed an interesting ability for self‐fluorination involving trifluoromethyl groups to give the P−F derivatives 13a,b . An X‐ray analysis and NMR spectroscopic data showed that molecules of 10a,b have different conformations in solution and in the crystal. Compounds 10a,b reacted further with 8 to give either the symmetrical diylide 16a or the P−F derivative 13b . The addition of hexafluoroacetone to 10a,b resulted in the formation of unsymmetrical diylides 19a,b . (© Wiley‐VCH Verlag GmbH, 69451 Weinheim, Germany, 2002)
