| Abstract: | Infrared spectroscopy shows that CaH(2) in liquid 1-ethyl-3-methyl-1H-imidazolium chloroaluminates reduces the cation in Lewis basic systems, does not affect the neutral salt, and forms AlCl(3)H(-) and eventually allanes in Lewis acidic systems. The AlCl(3)H(-) species can be determined by UV-vis spectroscopy through its reaction with 2,3-dichloro-1,4-naphthoquinone to form an alkoxide. While AlCl(3)H(-) reacts with protic species to give H(2), its electrochemical oxidation proceeds through H(ads), some of which is oxidized to H(+), which can be electrochemically reduced. |
