POUR PREPARER CES CATALYSEURS D'HYDROGENATION DE FORMULE:MALH(OR)ON FAIT REAGIR UN COMPOSE D'HYDRURE AYANT LA FORMULE:M(ALH)EVENTUELLEMENT COMPLEXE AVEC UNE BASE DE LEWIS, AVEC UN ALCOOL AYANT DE 1 A 20ATOMES DE CARBONE. DANS CETTE FORMULE M EST UN METAL ALCALINOTERREUX, R EST UN RADICAL ALKYLE, CYCLOALKYLE OU ARYLE, ET N VA DE 0,5 A 3,5.UTILISATION DES CATALYSEURS POUR PREPARER DES ALCOOLS, DES AMINES, DES SULFURES, ETC. PAR REDUCTION D'ACIDES, D'AMIDES OU DE SULFOXYDES, RESPECTIVEMENT. Alkoxy-hydride derivatives having the formula M [A1H4-n(OR)n]2, wherein M is an alkaline earth metal and 0.5 </= n </= 3.5, and complexes thereof with a Lewis base, are obtained by reacting a hydride having the formula M (A1H4)2, or a complex thereof with a Lewis base, with an alcohol containing up to 20 carbon atoms. The derivates and complexes are useful as catalysts for the reduction of organic compounds.
