A novel fluorous polystyrene (FPS) MR-resin was applied to a fluorous solid-phase (FSP) reaction. The MR-FPS resin actually was developed previously and possessed excellent chemical resistance to acids and alkalis, and a fluorous-tagged compound was homog

Mono-dispersed poly(ethylene glycols) (PEGs) are of great value in the development of biopharmaceuticals. However, tedious synthesis limits the availability of mono-dispersed PEGs. To address this issue, a fluorous synthesis of mono-dispersed PEGs, discretely PEGylated surfactants and 19F magnetic resonance imaging (MRI) agents has been developed. During the synthesis, both fluorous and normal phase silica gel-based solid-phase extractions were successfully employed to simplify the purifications. This synthesis provided an easy access to valuable mono-dispersed PEGs and related molecules for biomedical application on multi-gram scales.
Efficient access to perfluoroalkylated aryl compounds by Heck reaction

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.
Thiol additions to acrylates by fluorous mixture synthesis: Relative control of elution order in demixing by the fluorous tag and the thiol substituent

All possible combinations of a series of three fluorous benzyl tags and three acrylates have been made. The resulting acrylate esters were combined in groups of three (one of each tag) and the resulting mixtures were reacted with a mixture of four thiols under standard conditions to effect conjugate addition. Analysis of the resulting libraries by fluorous hplc showed a primary separation based on the tag and revealed reliable secondary separations based on the thiol and the acrylate. The primary and secondary separations were used together in a preparative 'mixture of mixtures' experiment in which one of the tagged acrylate mixtures was reacted with a mixture of three thiols. The resulting nine component mixture was demixed by fluorous and reverse phase hplc and then detagged to give all nine final products in pure form.
Perfluoroalkyl-substituted arylphosphanes as ligands for homogeneous catalysis in supercritical carbon dioxide

The solubility of complexes is one decisive factor for their use as homogeneous catalysts in supercritical carbon dioxide (scCO2). Complexes with perfluoroalkyl-substituted arylphosphane ligands (shown schematically on the right), which can be
