Pentacoordinated Rhodium(I) Complexes Supported by Coumarin-Functionalized N-Heterocyclic Carbene Ligands 2018 Access copy available to the general public Unrestricted New coumarin-Tethered benzimidazolium (BzICouRHCl) and imidazolium (ICouRHCl) salts have been prepared as precursors for coumarin-NHC rhodium(I) complexes RhCl(NHC)(cod). Trigonal bypiramidal pentacoordinated bis-coumarin-NHC rhodium(I) species, RhCl(NHC)2, can be obtained by heating rhodium-cod derivatives in the presence of coumarin-Azolium salts and a base. These unusual species are stabilized by coordination of the unsaturated bond of both coumarin moieties by the same enantioface. The allyl substituent on doubly functionalized NHC competes for coordination with coumarin wingtips. DFT calculations upon coordination of the olefin moieties support the experimental results. info:eu-repo/grantAgreement/ES/CSIC/201680I011 info:eu-repo/grantAgreement/ES/DGA/E07 info:eu-repo/grantAgreement/ES/MINECO-FEDER/CTQ2013-42532-P info:eu-repo/grantAgreement/ES/MINECO/IJCI-2015-27029 info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 4.1 2018 CHEMISTRY, ORGANIC 11 / 57 = 0.193 2018 Q1 T1 CHEMISTRY, INORGANIC & NUCLEAR 5 / 45 = 0.111 2018 Q1 T1 1.473 2018 Inorganic Chemistry 2018 Q1 Physical and Theoretical Chemistry 2018 Q1 Organic Chemistry 2018 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion (orcid)0000-0002-3666-5800 Di Giuseppe, A.
