ABSTRACT:
Catalyst compositions based on amorphous partially dehydrated zirconium hydroxide which are doped with from 0.01 to 20 atom percent of copper and/or from 0.01 to 20 atom percent of nickel, in each case based on zirconium, and have a specific surface area by the BET method of at least 50 m.sup.2 /g. The catalyst compositions are suitable, in particular, as the catalyst in hydrogen transfer reactions, such as, the Meerwein-Ponndorf-Verley reduction or the Oppenauer oxidation. The preparation of 3-hydroxyquinuclidine of the formula: ##STR1## involves reaction of quinuclidin-3-one with a secondary alcohol in the presence of the amorphous partially dehydrated zirconium hydroxide.
