Over the last few years interest in supported ionic liquid (IL) catalysis has been growing. This is due to the increased selectivity and catalytic activity obtained in IL based systems compared with molecular solvents coupled with the advantages of solid catalyst in terms of separation. In this thesis, the effect of supported ionic liquid catalysis will be examined for various different reactions including the hydrogenation of citral and cinnamaldehyde, the Diels-Alder, Mukaiyama aldol and carbonyl-ene reactions. Solid catalyst ionic liquid layers (SCILL) catalysts and Ionic polymers (IP) were used for the hydrogenation of citral and cinnamaldehyde. Overall a Pd/Ab03 with and without an IL produced significantly higher selectivities and conversions compared with a Pd/C catalyst. The IP catalysts were shown to greatly increase the selectivity. The IP synthesised from the commercial Amberlite 910, produced the best results for both substrates achieving high selectivities up to 99%.
