Dynamic Configuration on a Chiral-at-Rhodium Catalyst Featuring a Flexible Tetradentate Ligand 2024 Access copy available to the general public Unrestricted The unique dynamic configuration of an enantioselective chiral‐at‐metal catalyst based on Rh(III) and a non‐chiral tetradentate ligand is described and resolved. At room temperature, the catalyst undergoes a dynamic configuration process leading to the formation of two interconvertible metal‐stereoisomers, remarkably without racemization. Density functional theory (DFT) calculations indicate that this metal‐isomerization proceeds via a concerted transition state, which features a trigonal bipyramidal geometry stabilized by the tetradentate ligand. Furthermore, the resolved enantiopure complex shows high catalytic enantioinduction in the Friedel‐Crafts reaction, achieving enantiomeric ratios as high as 99 : 1. info:eu-repo/grantAgreement/ES/DGA/E05-23R info:eu-repo/grantAgreement/ES/MCIU-AEI-FEDER/PID2021-122406NB-I00 info:eu-repo/grantAgreement/ES/MCIU/RED2018-102574-T info:eu-repo/grantAgreement/ES/MICINN/CTQ2018-095561-BI00 info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 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/acceptedVersion Castillo, Javier (orcid)0000-0002-6160-3046 Viguri, Fernando Universidad de Zaragoza (orcid)0000-0003-4196-5856 Carmona, Daniel (orcid)0000-0002-1735-6439 Passarelli, Vincenzo (orcid)0000-0001-8054-2237 Lahoz, Fernando J.
