This dissertation is divided into three chapters. In the first chapter the activation of hydrogen molecules by splitting between bifunctional sterical demanding Lewis acid and Lewis base compounds such as 1,6-bis(bis(perfluorophenyl)boryl) hexane and 1,3-bis (diphenylphosphino)propane was investigated. The low storage capacity using large substitution to improve sterical effect led us to explore the amine borane derivatives, which are explained in chapter two.
Due to the high storage capacity of hydrogen in aminoborane derivatives, the ionic liquid methylguanidinium borohydride (N3H8C)C+BH4- (m.p. -5 °C, ρ (20 °C) = 0.95 g/ml) is presented. Under both thermal and catalytic conditions it releases 9.0 wt % H2.
In the third section, ionic liquids based on methyl guanidinium cation with different anions such as tetrafluoroborate were developed. We replaced these anions with transition metal anions to investigate hydrogen bonding and catalytic activity of ionic liquids. The catalytic activity is investigated particularly with respect to the cyclization of CO2 and propylene oxide forming cyclic carbonates.
