Simple and generic approaches to fluorous soluble ligands have been developed and applied to the synthesis of various fluorinated arylphosphines including polymeric ones. The utility of some of these ligands has been demonstrated in catalysis in supercritical CO2 (scCO2) and fluorous solvents.

Efficient introduction of perfluorinated tails onto aromatic rings has been achieved by Heck reaction between perfluoroalkenes and arenediazonium salts, catalysed by palladium acetate. Subsequent transition metal catalysed hydrogenation of the double bond afforded a large variety of aromatic compounds bearing an affinity for fluorous solvents. Formation of perfluoroalkylated phosphane ligands and their use in palladium-catalysed coupling between potassium trifluoro(vinyl)borates and diazonium salts is also described, allowing an easy separation and recycling of the catalytic system.
