Abstract
A process for making methyl esters in high yields is provided. The process comprises contacting aliphatic or aromatic aldehydes and methanol with an iron catalyst, to catalyze the dehydrogenative coupling between aliphatic or aromatic aldehydes and methanol. The reaction is highly selective (<99.9%) toward the formation of methyl esters over homoesters and alcohols and operates at temperatures of less than 100° C. for 2-8 hours.
