Abstract:
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.

Claim (Index 4):
A method for preparing highly reactive alkali metal or alkaline metal hydrides MH n * where n=1or 2 corresponding to the valence of the metal M, characterized in that metals M of the first or second period of the periodic of table of elements are reacted with a compound of general formula M 1 x [M 2 (A 1 y A 2 z ) 3+x ] b  or in the presence of finely dispersed, highly reactive metal M 2+  with a mean particle size D 50  in the range from 0.01 to 100 \u03bcm in the presence of hydrogen gas or another source of hydrogen according to wherein M 1 =an alkali metal selected from the group consisting of Li, Na, K, Rb, Cs, an alkaline earth metal selected from the group consisting of Be, Mg, Ca, Sr, Ba, or an element from the group of the rare earths selected from the group consisting of Sc, Y, La, Ce, Pr, Nd, Pm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu; x=0 or 1; n=1 or 2, corresponding to the valence of the metal M; b=the valence of M 1 ; M 2 =an element of the 3rd main group of the periodic table of elements, selected from the group consisting of B, Al, Ga, In;\n A 1 =H or an alkyl group, branched or unbranched, containing 1-18 C atoms, wherein the up to four A groups can be identical or different; \n A 2 =an alkoxy residue OR where R=alkyl with 1-8 C atoms, a dialkylamino residue \u2014NR 2  where R=alkyl with 1-8 C atoms or a halogen from Cl, Br, I; \n y can assume the value 1, 2 or 3, and wherein y+z=3.
