Abstract
A method for the production of alkoxyalanates of alkaline earth metals is disclosed, which comprises the step of reacting an alkali metal alanate, an alkaline earth metal halide and an aluminum alcoholate.
Claims6
A process for synthesizing alkoxyalanates of alkaline earth metals of the formula:
- M[AlH.sub.4-n (OR).sub.n ].sub.2.mB
- in which M represents the alkaline earth metal, OR represents an alkoxy group of a primary, secondary or tertiary alcohol in which R is an aliphatic, cycloaliphatic or aromatic radical, n is a number between 0.5 and 3.5, B is a Lewis base, m is a number between 0 and 4, and R can also contain functional groups such as OR', SR', NR'.sub.2, said R' being the same as R consisting of reacting together (a) an alkali metal alanate, (b) a halide of the alkaline earth metal, (c) an alcoholate of the alkaline earth metal, and (d) an aluminium alcoholate.
