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 3):
A method for preparing highly reactive alkali metal or alkaline earth metal hydrides MH n * where n=1 or 2 corresponding to the valence of the metal M, characterized in that metals M of the first or second periods of the periodic table of elements are reacted with a compound of general formula M 1 x [M 2 H 3+x ] b  under inert conditions or under hydrogen atmosphere according to\n M+o/ 6 M 1 x [M 2 H 3+x ] b \u2212\u2212>MH n *+p/ 6 M 1 H m *+q/ 6  M 2 * , 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; x=0 or 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; b=the valence of M 1 ; m=1 or 2, corresponding to the valence of the metal M 1 ; n=1 or 2, corresponding to the valence of the metal M; and in the case in which x=0, p=0, and for M=alkali element, o and q=2; for M=alkaline earth element, o and q=4 and in the case in which x=1: for M and M 1 =alkali metals, o, p, q=2; for M and M 1 =alkaline earth metals, o, p=2, and q=4; for M=alkali metal and M 1 =alkaline earth metal, o, p=1, and q=2, and for M =alkaline earth metal and M 1 =alkali metal, o, p, q=4.
