Abstract: Boron chelate complexes of the general formula 1

Abstract: The invention relates to a method for producing compounds of general formula (A) by reacting an alkali metal hydride with a compound (B) during which the reaction is carried out in the presence of a catalyst that contains boron, whereby: M represents Li, Na, K, Rb or Cs; E represents B or Al, and; X1, X2, X3, independent of one another, represent a secondary or tertiary alkyl group, which is comprised of 2 to 10 atoms, or represent a phenyl group which itself can be alkyl-substituted or they represent an alkoxy group, and the catalyst, which contains boron, or the conversion product thereof with MH is capable of acting as a hydride transfer agent.

Abstract: A process is described for the preparation of lithium iodide solutions by reacting a lithium-containing substance with elemental iodine, the lithium iodide being prepared in an aprotic solvent that can be used as a solvent in a liquid electrolyte solution.

Abstract: The invention relates to tris-(oxalato)phosphates of the general formula M[P(C2O4)3] wherein M=H, a metal or N(R1R2R3R4), where R1, R2, R3, R4, are independently H or an alkyl group comprising 1 to 8 C atoms. The invention also relates to a method for preparing such compounds as well as to their use.

Abstract: The invention relates to the novel lithium bisoxalatoborate compound, and to a method for producing this compound, on the basis of a lithium compound, an oxalic acid or an oxalate, and a boron compound. The invention also relates to another production method on the basis of lithium boron hydride and oxalic acid, and to the use of lithium bisoxalatoborate as a conducting salt in lithium-ion batteries.

Abstract: The invention relates to a method for producing alkali metal alcoholates by reacting alcohol with alkali metal in an aprotic, organic solvent in the presence of an H acceptor such as e.g. isoprene, butadiene, styrene or methyl styrene.

Abstract: The invention relates to a method for producing organo alkali-metal compounds by reacting metal lithium, sodium or potassium with organic compounds containing at least one acidic CH bond in a solvent. The inventive method is characterized in that the reaction is carried out in the presence of a hydrogen acceptor, wherein 0.5 to 5 moles of the hydrogen acceptor are used per mole of acid hydrogen, which hydrogen can be replaced by lithium, sodium or potassium, whereby 1 to 3, moles of lithium, sodium or potassium are used per mole of acid hydrogen and the acid CH bond has a pKa value of 10 to 30. Cyclopentadiene, indene, fluorene and substitution products thereof, or monosubstituted alkynes or methane substitution products, are preferred CH acid organic compounds. Hydrocarbons used as hydrogen acceptors include these with at least one CC double bond in conjugation with either another CC double bond or with a monocyclic aryl radical.

Abstract: The method of making the stable non-pyrophoric solution containing a lithium diorganoamide of the formula, LiNR'R" wherein R' and R" each have from 2 to 6 carbon atoms, in an inert liquid hydrocarbon solvent includes mixing a secondary amine including the R' and R" groups and an alcohol having 3 to 6 carbon atoms with a lithium granulate or powder in the hydrocarbon solvent and reacting the secondary amine, the alcohol and the lithium with addition of an electron acceptor compound, advantageously styrene or isobutene, to form the stable non-pyrophoric solution containing the lithium diorganoamide and a lithium alkoxide having 3 to 6 carbon atoms.
