The new ruthenium( II)-NHC complexes were applied to transfer hydrogenation of acetophenone derivatives and aldehydes using 2-propanol as a hydrogen source and KOH as a co-catalyst. The results show that the corresponding alcohols could be obtained in good yield with high catalyst activity (up to 100%) under mild conditions. [RuL1(p-cymene)Cl-2] (3a) is much more active than the other complexes in transfer hydrogenation. Reactions, catalyzed by 3a-c, showed the highest reaction rates and yields of alcohol when the substrates bear more electron-withdrawing substituents. All new compounds were characterized by IR, elemental analysis, LC-MS (ESI), and NMR spectroscopy.eninfo:eu-repo/semantics/closedAccessRutheniumSilverN-Heterocyclic carbineTransfer hydrogenationTransmetalationArticle6771236124810.1080/00958972.2014.9112912-s2.0-84901626848Q3WOS:000337244100010Q2
