Readily synthesized, well-defined N-heterocyclic carbene-based ruthenium(II) hydride complexes were developed for amide synthesis from alcohols and amines under base-free conditions. Diverse amides were synthesized in fair-to-excellent yields. In the case of secondary amines, where direct dehydrogenative amidation is not feasible, a catalytic amount of a base was required to promote the transamidation of esters, which are byproducts of alcohol dimerization. © 2015 Elsevier Ltd.
