Reversible Hydride Migration from C5Me5 to RhI Revealed by a Cooperative Bimetallic Approach. Angewandte Chemie International Edition, 59 (47), 20863-20867. https://doi.org/10.1002/anie.202008442.1433-78511521-3773https://hdl.handle.net/11441/140024The use of cyclopentadienyl ligands in organome-tallic chemistry and catalysis is ubiquitous, mostly due to theirrobust spectator role. Nonetheless, increasing examples of non-innocent behaviour are being documented. Here, we provideevidence for reversible intramolecular C H activation at onemethyl terminus of C5Me5in [(h-C5Me5)Rh(PMe3)2] to forma new Rh H bond, a process so far restricted to early transitionmetals. Experimental evidence was acquired from bimetallicrhodium/gold structures in which the gold center binds either tothe rhodium atom or to the activated Cp* ring. Reversibility ofthe C H activation event regenerates the RhIand AuImonometallic precursors, whose cooperative reactivity towardspolar E H bonds (E=O, N), including the N H bonds inammonia, can be understood in terms of bimetallic frustration.application/pdf5 p.engAtribución 4.0 Internacionalhttp://creativecommons.org/licenses/by/4.0/info:eu-repo/semantics/articleinfo:eu-repo/semantics/openAccesshttps://doi.org/10.1002/anie.202008442
