We developed a ruthenium-catalyzed reductive estersynthesisfrom aldehydes or ketones and carboxylic acids using carbon monoxide as a deoxygenative agent. Multiple factors influencing the outcome of the reaction were investigated. Best results were obtained for commercially available and inexpensive benzene ruthenium chloride; as low as 0.5 mol % of the catalyst is sufficient for efficient reaction

A rhodium‐catalyzed reductiveesterification of carboxylicacids with carbonyl compounds was developed. This protocol fits a variety of carboxylicacids and aldehydes, opening the short way from industrial bulk compounds to valuable esters.

environmental friendly process to selectively acetylate primary alcohols was demonstrated. The esterification process consists of treatment of a primary alcohol in the presence of immobilized C. antarctica lipase (Novozyme-435) in ethyl acetate at room temperature. Primary alcohols were acetylated in the presence of secondary alcohols and phenols.
