In 2005, Caffyn and co-workers published a method for the synthesis of P(R f ) 3 compounds, based on the reaction of Me 3 SiR f with P(OR) 3 (R = Ph, p-C 6 H 4 CN). 10 Subsequently Togni et al. reported that CF 3 -containing phosphanes may be prepared from Ph 2 PH or Ph 2 PSiMe 3 and CF 3 -containing hypervalent iodine compounds. 11 Both of these methods benefit from the commercial availability of Me 3 SiCF 3 , unfortunately other Me 3 SiR f reagents ...
