Reduced graphene oxides as carbocatalysts in acceptorless dehydrogenation of N-heterocycles 2021 Access copy available to the general public Unrestricted The catalytic properties of graphene-derived materials are evaluated in acceptorless dehydrogenation of N-heterocycles. Among them, reduced graphene oxides (rGOs) are active (quantitative yields in 23 h) under mild conditions (130 °C) and act as efficient heterogeneous carbocatalysts. rGO exhibits reusability and stability at least during eight consecutive runs. Mechanistic investigations supported by experimental evidence (i.e., organic molecules as model compounds, purposely addition of metal impurities and selective functional group masking experiments) suggest a preferential contribution of ketone carbonyl groups as active sites for this transformation. © info:eu-repo/grantAgreement/ES/DGA/E31-20R info:eu-repo/grantAgreement/ES/MICIU/RTI2018-098237-B-C21 info:eu-repo/grantAgreement/ES/MICIU/RTI2018-098237-B-C22 info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 13.7 2021 CHEMISTRY, PHYSICAL 19 / 165 = 0.115 2021 Q1 T1 4.202 2021 Chemistry (miscellaneous) 2021 Q1 Catalysis 2021 Q1 20.8 2021 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Ventura-Espinosa D.
