Liquid Lewis acids based on boron(lll), Aluminium(lll), Gallium(lll), and antimony (III) chlorides were all synthesised and characterised by spectroscopic and physical measurements. These liquid Lewis acids fall into 2 categories, Al and Ga based liquid coordination complexes (LCCs) and B and Sb based ionic liquids. The ionic liquids were synthesised to have a Lewis acidic cation, as halometallate ionic liquids typically have Lewis acidic anions. Boron based borenium ionic liquids, and liquid coordination complexes were both shown to be highly acidic, meaning potentially be utilised much like chloroaluminate ionic liquids, which have received much attention for their acidic catalytic abilities. The strategy used to synthesise borenium ionic liquids was successfully applied to SbCI3 as well. The successful synthesis of commercial quality lubricants by 1-decene oligomerisation was achieved using both LCC catalysts and with borenium ionic liquids. These catalysts represent safer, “greener” alternatives to the current industrial catalyst, BF3.
