This project combines two topical areas: Main Group catalysis and ionic liquids, based on previous work by the group on the development of borenium ionic liquids. This research will involve designing and synthesising ionic liquids displaying FLP activity, characterising them and exploring their catalytic applications. The aim is to further the development of new ionic liquids with highly Lewis acidic borenium cations, for applications in catalysis, in particular as frustrated Lewis pairs (FLP). A study into the design of ionic liquids FLP systems that can activate hydrogen will be undertaken and applied to the reduction of organic substrates. Ionic liquid FLPs have many advantages over FLP chemistry in organic solvents, in particular high concentration of active species and negligible volatility. Initial studies will be carried out homogenously, at NMR scale, followed by immobilisation of the IL-FLPs on solid supports and moving onto heterogenous catalysis. Activation of other small molecules, in particular CO2 and methane, will be investigated.

该项目结合了两个主题领域：Main Group催化和离子液体，基于该小组之前在硼离子液体开发方面的工作。这项研究将包括设计和合成具有FLP活性的离子液体，表征它们并探索它们的催化应用。目的是进一步发展具有高刘易斯酸性硼离子阳离子的新型离子液体，用于催化，特别是作为受挫刘易斯对（FLP）。研究设计离子液体FLP系统，可以激活氢将进行和应用于有机底物的还原。与有机溶剂中的FLP化学相比，离子液体FLP具有许多优点，特别是活性物质浓度高，挥发性可忽略不计。初步研究将在核磁共振尺度上均匀进行，随后将IL-FLPs固定在固体载体上，然后进行多相催化。其他小分子的活化，特别是二氧化碳和甲烷，将被研究。
