Abstract: | 1-Nonanol and alkyl 9-hydroxynonanoates were more readily prepared by hydrogenation of the respective isolated aldehydes than
by direct hydrogenation of products from reductive ozonolysis of oleate esters. Hydrogenation with nickel catalysts and aprotic
solvents reduced the isolated aldehydes in good yield with a minimum of side reactions. Although the noble metal catalyst
and hydroxylic solvent systems frequently used in similar reductions were also effective, they required a promoter that fortuitously
catalyzed hydrolysis of acetals that formed during hydrogenation. Direct hydrogenation of the ozonolysis products resulted
in side reactions and a mixture of products difficult to separate.
