N-heterocyclic carbene based ruthenium complex was developed as a highly active precatalyst for the directamidesynthesisfromalcohols and secondary amines. Notably, reaction of 1-hexanol and dibenzylamine afforded 60% of the corresponding amide using our catalytic system, while no amide formation was observed for this reaction with the previously reported catalytic systems. Unlike the previously reported
