The invention relates to powdery, highly reactive alkali and alkaline earth hydride compounds, and to mixtures with elements of the third main group of the periodic table of elements (PTE) and to the preparation thereof by reacting alkali or alkaline earth metals in the presence of finely dispersed metals or compounds of the third main group of the PTE, wherein the latter have one or more hydride ligands or said hydride ligands are converted in situ, under the prevailing reaction conditions, i.e., in the presence of hydrogen gas or another H source, into hydride species, and to the use thereof for the preparation of complex hydrides and organometallic compounds.

Highly reactive metal hydrides, process for their preparation and use

One or more concentrated low-viscosity solutions of alkaline earth alkoxide compounds M(OCHR)(OR)[O(CHR)ORin mixture with a metal alkyl compound M(RR) in an aprotic solvent and related methods are disclosed herein.

Low-viscosity solutions of alkaline-earth metal alkoxides in aprotic solvents, method for the production of same and use for the production of ziegler-natta catalysts

This invention provides a method for producing organometallic compounds RM (M=alkali or alkaline earth element, R=alkyl residue) where n=valence of the metal M- and R=alkyl residue with 2 to 18 C atoms. In the method of this invention, an olefin is hydrometalated in an alkyl methyl ether, or in a solvent mixture containing an alkyl methyl ether, by means of the metal M and in the presence of a hydrogen source and in the presence of a transition metal catalyst, wherein the molar ratio between alkyl methyl ether and metal M is at least 0.01:1 and at most 50:1.

A solution of a mixed alkaline earth alkoxide compound with an aluminum compound in an aprotic solvent, and methods of making and using them.

Low-viscosity concentrated solutions of alkaline earth metal alkoxides in aprotic solvents and processes for preparation thereof

The invention relates to a novel process for preparing lithium sulfide and to the use thereof, wherein a reaction of lithium-containing strong bases with hydrogen sulfide is undertaken in an aprotic organic solvent within the temperature range from &#x2212;20 to 120&#xb0; C. under inert conditions. The lithium sulfide obtained by the process is used as a positive material in a galvanic element or for the synthesis of Li ion-conductive solids, especially for the synthesis of glasses, glass ceramics or crystalline products.
