Depending on the coordination strategy, a monometallic [Ru(NNC)(CO3)(PPh3)] complex, or the [Ru(μ-Cl)(NNC)]2(2Cl−) dimer, was obtained. A di-silver complex in which two ligands are monocoordinated to the metal center through the NHC groups was also obtained and characterised. The dimetallic ruthenium complex reacts with alcohols yielding a monohydride species. The preliminary studies on the catalytic activity of the ruthenium dimer indicate that the complex is active in the reduction of ketones and aldehydes under transfer hydrogenation conditions.2015http://zaguan.unizar.es/record/10837310.1039/c5qo00137dhttp://zaguan.unizar.es/record/108373oai:zaguan.unizar.es:108373info:eu-repo/grantAgreement/ES/MINECO/CTQ2014-51999-Pinfo:eu-repo/grantAgreement/ES/MINECO/FPDI-2013-16525Organic Chemistry Frontiers 2, 8 (2015), 936 - 941All rights reservedhttp://www.europeana.eu/rights/rr-f/info:eu-repo/semantics/openAccess
