Reduction of Halomethanes with Lithium Aluminum Hydride
A study has been made of t he reactions of lithium aluminum hydride with methyl bromide, methylene chloride, meth ylene bromide, methylene iodide, chloroform, bromoform, and carbon t etrachloride. Except for hydrogen and unreacted h alida, essentia lly pure methane was formed in each case. The amount of hydrogen evolved increased with the n umber of halogen atoms in the molecule, reaching a max...
متن کاملRegeneration of lithium aluminum hydride.
Lithium aluminum hydride (LiAlH(4)) is a promising compound for hydrogen storage, with a high gravimetric and volumetric hydrogen density and a low decomposition temperature. Similar to other metastable hydrides, LiAlH(4) does not form by direct hydrogenation at reasonable hydrogen pressures; therefore, there is considerable interest in developing new routes to regenerate the material from the ...
متن کاملAluminum Hydride Chemistry
Anion photoelectron spectroscopy and density functional theory were employed to study aluminum hydride clusters, AlnHm (4 e n e 8, 0 e m e 10). Photoelectron spectra revealed that Al4H4, Al4H6, and a family of species with general formula AlnHn+2 (5 e n e 8) have small adiabatic electron affinities and large HOMO-LUMO gaps (ranging from 0.5 to 1.9 eV) relative to those of their stoichiometric n...
متن کاملBuckyball-, carbon nanotube-, graphite-, and graphene-enhanced dehydrogenation of lithium aluminum hydride.
Compared to C60, carbon nanotubes, and graphite, graphene more effectively lowers the dehydrogenation temperature and improves the dehydrogenation kinetics of LiAlH4. With 15 wt% graphene incorporation, the initial hydrogen release temperature is ~80 °C (60 °C lower than that of pristine LiAlH4).
متن کاملReduction of 2-chloro-N-phenylpropanamide and 2-methyl-N-phenylaziridine with lithium aluminium hydride.
The reduction of 2-chloro-N-phenylpropanamide with LiAlH(4) has been re-examined. In contrast to previous findings, we obtain in almost equal quantities two amines from this reaction, namely N-propylaniline and the rearranged product N-isopropylaniline. 2-Methyl-N-phenylaziridine is an intermediate in the reduction and can be isolated from reactions with less LiAlH(4). Reduction of 2-methyl-N-p...
