The individual lamellae of the dirhodium-bdc frameworks are stacked as parallel sheets, which are randomly oriented or slightly ordered. As inorganic building blocks Rh2(TFA)4 and Rh2(OAc)4, and as organic linker benzene 1,4-dicarboxylate (bdc) are employed. The successful synthesis of the Rh2-bdc(Tf) and Rh2-bdc(Ac) catalysts is proven by ATR-IR, XPS and 13C CP MAS NMR. Residual trifluoroacetate species are investigated by quantitative 19F MAS NMR which further reflects the configuration of trifluoroacetate in the obtained Rh2-bdc(Tf), and defects in the structure. DR-UV-vis and XPS demonstrate that the oxidation state and the Rh-Rh single bond in the dirhodium node are maintained during the ligand substitution process. The stability and reusability of the catalysts are verified by TG-DTA measurements and leaching tests. The catalysts show similar catalytic efficiency as the homogeneous catalyst in the model cyclopropanation between ethyl diazoacetate (EDA) and styrene.","lang":"eng"}],"date_created":"2026-02-07T15:58:38Z","author":[{"full_name":"Liu, Jiquan","last_name":"Liu","first_name":"Jiquan"},{"first_name":"Claudia","last_name":"Fasel","full_name":"Fasel, Claudia"},{"last_name":"Braga-Groszewicz","full_name":"Braga-Groszewicz, Pedro","first_name":"Pedro"},{"full_name":"Rothermel, Niels","last_name":"Rothermel","first_name":"Niels"},{"first_name":"Aany Sofia","last_name":"Lilly Thankamony","full_name":"Lilly Thankamony, Aany Sofia"},{"first_name":"Grit","full_name":"Sauer, Grit","last_name":"Sauer"},{"first_name":"Yeping","last_name":"Xu","full_name":"Xu, Yeping"},{"full_name":"Gutmann, Torsten","id":"118165","last_name":"Gutmann","first_name":"Torsten"},{"first_name":"Gerd","last_name":"Buntkowsky","full_name":"Buntkowsky, Gerd"}],"volume":6,"date_updated":"2026-02-17T16:15:20Z","publisher":"The Royal Society of Chemistry","doi":"10.1039/C6CY00915H","title":"Heterogeneous self-supported dirhodium(ii) catalysts with high catalytic efficiency in cyclopropanation - a structural study","issue":"21","publication_identifier":{"issn":["2044-4753"]},"citation":{"chicago":"Liu, Jiquan, Claudia Fasel, Pedro Braga-Groszewicz, Niels Rothermel, Aany Sofia Lilly Thankamony, Grit Sauer, Yeping Xu, Torsten Gutmann, and Gerd Buntkowsky. “Heterogeneous Self-Supported Dirhodium(Ii) Catalysts with High Catalytic Efficiency in Cyclopropanation - a Structural Study.” <i>Catalysis Science &#38; Technology</i> 6, no. 21 (2016): 7830–7840. <a href=\"https://doi.org/10.1039/C6CY00915H\">https://doi.org/10.1039/C6CY00915H</a>.","ieee":"J.
