The solid structure of 3 evidenced its dinuclear nature, being a rare example of an iridium species with triflate groups acting as bridges. The 3-catalyzed reduction of CO2 with HSiMe(OSiMe3)2 affords a mixture of the corresponding silylformate and methoxysilane together with the silylcarbonate CH3OCO2SiMe(OSiMe3)2 (4a). This is the first time that the formation of silylcarbonates has been observed from the catalytic reduction of CO2 with silanes. Analogous behaviour has been observed when HSiMe2Ph and HSiMePh2 were used as reductants. info:eu-repo/grantAgreement/ES/DGA-FSE/E42-17R info:eu-repo/grantAgreement/ES/MICINN/PGC2018-099383-B-I00 info:eu-repo/semantics/openAccess by-nc http://creativecommons.org/licenses/by-nc/3.0/es/ 3.361 2020 CHEMISTRY, MULTIDISCIPLINARY 81 / 178 = 0.455 2020 Q2 T2 0.746 2020 Chemistry (miscellaneous) 2020 Q1 Chemical Engineering (miscellaneous) 2020 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion García-Orduña, Pilar Universidad de Zaragoza (orcid)0000-0002-7063-1292 Lahoz, Fernando J.
