Abstract

Pincer ruthenium complexes bearing a monodentate N-heterocyclic carbene ligand have been used as powerful hydrogenation catalysts. With an atmospheric pressure of hydrogen gas, aromatic, heteroaromatic, and aliphatic esters as well as lactones were converted into the corresponding alcohols.
