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 کاملDibenzo-18-crown-6–picric acid–water (1/2/3)
In the crown ether ring of the title compound, C(20)H(24)O(6)·2C(6)H(3)N(3)O(7)·3H(2)O, the O-C(H(2))-C(H(2))-O torsion angles indicate a gauche conformation of the ethyl-eneoxy units, while the C-O-C-C torsion angles indicate planarity of these segments; the dihedral angle between the two benzene rings is 44.53 (13)°. In both picric acid mol-ecules, one of the nitro groups is twisted away from...
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...
متن کاملCrystal structure of 1:1 complex crystal between 4-(3-methoxybenzyloxy)-6-methyl-2-pyrone and maleimide.
molecules are one of the important current topics because of unusual and interesting results.1,2 We have reported the solidstate [2+2]photocycloaddition reactions of 1:1 complex crystals between 2-pyrone derivatives and maleimide (2) to afford highly stereoselective cycloadducts.2 As a part of our continuing program, 1:1 complex crystal formation between 4(3-methoxybenzyloxy)-6-methyl-2-pyrone ...
