Bis[4-(3,3,4,4,5,5,5-heptafluoro-2,2-bis(trifluoromethyl)pentyl)phenyl]phenylphosphine
Bis[4-(3,3,4,4,5,5,5-heptafluoro-2,2-bis(trifluoromethyl)pentyl)phenyl]phenylphosphine (CAS 322647-83-6; C32H17F26P; molar mass 926.41 g/mol) is a fluorous ("Rf-tagged") triarylphosphine ligand bearing two heavily fluorinated alkyl ponytails. The perfluoroalkyl chains make it preferentially soluble in fluorous media, so it is used chiefly as a recyclable ligand for transition-metal catalysis in fluorous and fluorous-biphasic synthesis. Tech Serve Solutions supplies it as a research-grade reagent, assay ≥90.0%, to laboratories and process developers worldwide.

Fluorous-phase catalysis ligand
The fluorinated ponytails confer high affinity for perfluorinated solvents, allowing the phosphine to act as a fluorous-soluble ligand in fluorous-biphasic and thermomorphic catalytic systems. This supports catalyst recovery and recycling by simple phase separation.
Transition-metal complex formation
As a triarylphosphine, it coordinates to soft transition metals such as palladium, rhodium and platinum to form organometallic complexes. The resulting fluorous-tagged complexes are studied as catalysts for homogeneous transformations.
Rf-tagged ligand for catalyst immobilisation
The perfluoroalkyl tags enable catalyst partitioning into a fluorous phase or onto fluorous supports, aiding separation of the catalyst from products. It is therefore used in research on immobilised and reusable homogeneous catalysts.
Specialty and exploratory synthesis
It serves as a building block and ligand in specialty organometallic and fluorous synthesis programmes. Use is principally at research and process-development scale rather than bulk manufacture.
