Well-defined N-heterocyclic carbene based ruthenium complexes were developed as highly active catalysts for direct amide synthesis from alcohols and amines. A catalytic amount of a base such as (KOBu)-Bu-t was essential to initiate the catalytic cycle. Activity of the Ru complexes was comparable with the reported tit situ Ru catalysts. These catalysts provided mechanistic insight suggesting it Ru hydride species as an active catalytic intermediate. The generation of the Ru hydride wits critical for the amidation of free aldehydes.
