Unformatted text preview: atom. Like acetal formation, this process is reversible and can be run in either direction depending on the ratio of amine (ammonia) to water in the solution. 4. Imines can be reduced as they are made to give amines if H2/Pd is added to the reaction. 5. Aldehydes are easily oxidized to carboxylic acids using H2CrO4 in H2O. 6. Aldehydes and ketones can be reduced by H 2 /Pd to give alcohols. (Watch for racemic mixtures!) Note that this method will also reduce any carbon-carbon double or triple bonds that happen to be in the molecule....
