New ruthenium (0) complexes with a cooperative diolefin diaminopropane (DAP) or dehydrogenated iminopropenamide ligand (IPA) were synthesized for comparison with their diaminoethane (DAE)/diazadiene (DAD) ruthenium analogs. These DAP/IPA complexes were efficient catalysts in dehydrogenation reactions of alk. aqueous methanol which proceeded under mild conditions (T=70 °C) and of higher alcs., forming corresponding carbonate and carboxylates, resp. The scope of reaction included an example of a 1,2-diol as model for biomass derived alcs. Their catalytic applications were extended to atom-efficient dehydrogenative coupling of alcs. and amines to amides. The reaction proceeded without any additives and was applicable to synthesis of formamides from methanol. Moreover, DAP/IPA complexes catalyzed hydrogenation of a series of esters, lactone, ketone, activated olefin, aldehyde and imine substrates. The diaminopropane Ru catalyst I exhibited higher activity compared to dehydrogenated β-ketiminate (IPA) and previously studied DAD/DAE based catalysts. The studies on their stoichiometric reactivity with relevance to their possible catalytic mechanisms and isolation and full characterization of key reaction intermediates were also presented.
