Abstract
A novel approach to the preparation of perfluorotail-functionalized triarylphosphines using a p-silyl substituent as the branching point has been developed. This approach enabled the attachment of between three and nine perfluorotails per phosphorus atom, resulting in the production of highly fluorous tris[p-(1H,1H,2H,2H-perfluoroalkylsilyl)aryl]phosphines, P[C6H4-p-SiMe3-n(CH2CH2CxF2x+1)n]3 (n = 1, 2, 3; x =
