Raspberry and ginger ketones have been synthesized in good yield by the hydrogenation of the corresponding unsaturated precursors 4-(4′-hydroxyphenyl)but-3-en-2-one and 4-(4′-hydroxy-3′-methoxyphenyl)but-3-en-2-one, respectively, using a freshly prepared suspension of nickel boride in methanol as catalyst.
