A process for producing alkyl esters by dehydrogenation of a primary alcohol using a homogenous catalyst system

摘要

The invention refers to a process for producing alkyl ester, especially for producing ethyl acetate, which comprises reacting a primary alcohol in the presence of a ruthenium-based homogeneous catalyst system containing a tridentate pincer ligand. A first homogenously catalyzed acceptorless dehydrogenation of alcohols to the corresponding alkyl esters was developed preferably the dehydrogenation of ethanol to ethyl acetate using a PNP pincer complex of ruthenium as the catalyst.
