Summary on Grant Application Form
Supported fluorous phase catalysis (SFPC) is a hybrid approach to the heterogenisation of homogeneous catalysts designed to overcome the disadvantages of supported phase and fluorous biphase catalysis (FBC) approaches, i.e. catalyst degradation, generic applicability, fiscal and environmental issues arising from large perfluorocarbon inventories. Preliminary work on SFPC using perfluoroalkylated silica supports has shown th activity similar to that in FBC with minimal catalyst leaching can be achieved, but, since all Si-OH functionalities in these supports cannot be capped, catalyst degradation is an issue. Here, we will evaluate perfluoroalkylated insoluble styrene based polymer supports in SFPC where catalyst degrada will not occur, and the validity of the SFPC approach will be investigated for a range of reactions using established fluorous phase soluble catalysts. ' perfluoroalkylated styrene supports will be fully characterised and prepared by two approaches: (i)derivatisation of commercial functionalised polyme supports e.g. Merrifield resins & (ii) copolymerisation of perfluoroalkylated styrene with 1,4divinylbenzene. Reactions including hydroformylation (Ho phosphine catalysts), oxidation (Pozzi salen and Knochel R-diketonate catalysts) and C-C coupling (Bannwarth phosphine catalysts) will be studied y activity. % catalvst loss and catalvst recycle compared directly with catalysis under conventional and biphase conditions.
