Universidad de Zaragoza The fluoride method: access to silver(III) NHC complexes 2024 Access copy available to the general public Unrestricted We have synthesized the first silver(III) carbene complexes, (CF3)3Ag(NHC), by direct reaction of the silver(III) fluoride precursor complex [PPh4][(CF3)3AgF] with different imidazolium salts. This novel methodology circumvents the use of free NHC molecules. The silver(III) carbene complexes thus prepared are unprecedented and show remarkable thermal stabilities. They display square-planar or square-pyramidal geometry. Following our calculations, the electronic structure of a model representative complex exhibits Inverse Ligand Field (ILF). The compounds reported herein are synthetic analogues of the elusive difluorocarbene and carbonyl species proposed as intermediates in the acidic decomposition of [Ag(CF3)4]−. The synthetic procedure reported is envisaged to enable access to carbene complexes of other late transition-metals in high oxidation states. info:eu-repo/grantAgreement/ES/DGA/E17-23R info:eu-repo/grantAgreement/ES/MICINN/PID2021-122869NB-I00 info:eu-repo/grantAgreement/ES/MINECO/BES-2016-078732 info:eu-repo/semantics/openAccess by-nc-nd https://creativecommons.org/licenses/by-nc-nd/4.0/deed.es 3.7 2024 CHEMISTRY, MULTIDISCIPLINARY 95 / 239 = 0.397 2024 Q2 T2 0.981 2024 Chemistry (miscellaneous) 2024 Q1 Organic Chemistry 2024 Q1 Catalysis 2024 Q2 6.7 2024 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Joven-Sancho, D.
