Reactivity of Ir–NSiN Complexes: Ir-Catalyzed Dehydrogenative Silylation of Carboxylic Acids 2018 Access copy available to the general public Unrestricted This work describes the results from the studies on the potential of [Ir(µ-Cl)(cod)]2 (cod=1,5-cyclooctadiene) as metallic precursor for the preparation of Ir(NSiN) complexes (NSiN=fac-bis-(pyridine-2-yloxy)methylsilyl). The reaction of [Ir(µ-Cl)(cod)]2 with bis-(pyridine-2-yloxy)methylsilane enabled the synthesis of [Ir(H)(Cl)(NSiN)(¿2-cod)] with an uncommon ¿2-coordination mode for the cod ligand. The application of Ir–NSiN species as catalysts precursors for the dehydrogenative silylation of carboxylic acids was also explored. The outcomes from these catalytic studies revealed a clear influence of the ancillary ligand on the catalytic activity of Ir–NSiN species. Thus, whereas [Ir(H)(CF3SO3)(NSiN)(coe)] shows poor catalytic activity, the related complex [Ir(H)(CF3CO2)(NSiN)(coe)] with a trifluoroacetate ligand was demonstrated to be a highly active catalyst precursor. info:eu-repo/grantAgreement/ES/DGA-FSE/E07 info:eu-repo/grantAgreement/ES/MINECO-FEDER/CTQ2013-42532-P info:eu-repo/grantAgreement/ES/MINECO-FEDER/CTQ2015-67366-P info:eu-repo/grantAgreement/ES/MINECO-FSE/PTA contract info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 4.495 2018 CHEMISTRY, PHYSICAL 43 / 148 = 0.291 2018 Q2 T1 1.472 2018 Catalysis 2018 Q1 Physical and Theoretical Chemistry 2018 Q1 Organic Chemistry 2018 Q1 Inorganic Chemistry 2018 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion (orcid)0000-0001-8727-3404 Garcés, K.
