Synthesis of Aldehydes from Primary Alcohols in Pharm.Chem.Dep. at Sohag University

Reduction of carboxylic acids can directly produce aldehydes

Primary alcohols can be oxidized to aldehydes using pyridinium dichromate (PDC) or pyridinium chlorochromate (PCC)

Aldehydes can be prepared by reducing acyl chlorides

Oxidation of tertiary alcohols gives aldehydes.

Reduction of esters directly produces carboxylic acids

Synthesis of aldehydes from nitriles involves oxidation reactions

Reduction of ketones gives secondary alcohols.

Reduction of aldehydes gives primary alcohols.

Ozonolysis of di-substituted alkene will give one molecule of ketone and one molecule of aldehyde.

2-Butene upon ozonolysis gives only ethanol.
