Methods for preparation of aldehydes from carboxylic acid esters, including unsaturated fatty acid esters and triacyl glycerides, are described. The methods include combining an ester with a silane reagent and a borane catalyst to form a mixed silyl acetal which is hydrolyzed to provide the aldehyde product. The reagents are combined in a controlled manner to limit the generation of heat and hydrogen gas. New procedures for hydrolysis of acetal intermediates and improved purification and recovery processes provide aldehyde products in excellent yield.
