Cooperative catalysis combining a transition metal with an N‐heterocyclic carbene is challenging due to strong binding of NHCstowards late transition metals. We report the first example of synergistic catalysis by a chiral NHC and a coordinatively unsaturated ruthenium compound. RuCl3 was found to mediate efficient aerobic oxidation of homoenolates generated from enals and the N‐heterocyclic carbene
