Iridium complexes catalysed the selective dehydrogenation of glucose to gluconic acid in water 2018 Access copy available to the general public Unrestricted We describe an unprecedented catalytic dehydrogenation of glucose by homogeneous catalysts. Iridium(iii) complexes containing the fragment [Cp*Ir(NHC)](2+) (NHC = N-heterocyclic carbene ligand) are shown to be very active and highly selective catalysts for the dehydrogenation of glucose to gluconic acid and molecular hydrogen. Glucose is converted to gluconic acid at a catalyst loading of 2 mol%, at reflux in water, without additives and with a selectivity of over 95%. Experimental evidence obtained by H-1 NMR spectroscopy and mass spectrometry (ESI/MS) reveals the formation of iridium coordinated to glucose and gluconic acid species. A plausible mechanism is proposed, based on the experimental evidence and supported by DFT calculations. info:eu-repo/grantAgreement/ES/DGA/E21 info:eu-repo/grantAgreement/ES/MINECO/CTQ2015-67461-P info:eu-repo/grantAgreement/ES/MINECO/CTQ2015-69153-C2-1-R info:eu-repo/grantAgreement/ES/MINECO/CTQ2015-69153-C2-2-R info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 9.405 2018 GREEN & SUSTAINABLE SCIENCE & TECHNOLOGY 2 / 35 = 0.057 2018 Q1 T1 CHEMISTRY, MULTIDISCIPLINARY 20 / 172 = 0.116 2018 Q1 T1 2.517 2018 Pollution 2018 Q1 Environmental Chemistry 2018 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Vicent, C.
