Intramolecular C-C Coupling Reactions of Alkynyl, Vinylidene, and Alkenylphosphane Ligands in Rhodium(III) Complexes 2016 Access copy available to the general public Unrestricted Electrophilic attack with methyl trifluoromethanesulfonate or tetrafluoroboric acid, to new alkynyl rhodium complexes containing alkenylphosphanes, leads to butenynyl coupling products or to the unprecedented rhodaphosphacycle complexes Rh(¿5-C5Me5){¿4-(P, C, C, C)-iPr2PCH2C(=CH2)C(CH2R)C=C(R)}]BF4] (R = Ph (11a), p-tol (11b)). These complexes 11a, b can be explained as a result of the coupling of three organic fragments in the molecule, the alkynyl, the vinylidene, generated in situ by reaction with HBF4 (A), and the C-C double bond from the alkenylphosphane. DFT computational studies on the formation of complex 11a suggest the 2 + 2] intramolecular cycloaddition between the double bond of the allylphosphane and the Ca-Cß of the vinylidene A as the most plausible pathway for this reaction. info:eu-repo/grantAgreement/ES/MICINN/CSD2007-00006 info:eu-repo/grantAgreement/ES/MINECO/CTQ2011-28641 info:eu-repo/grantAgreement/ES/MINECO/MAT2015-68200-C2-1-P info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 3.862 2016 CHEMISTRY, ORGANIC 12 / 59 = 0.203 2016 Q1 T1 CHEMISTRY, INORGANIC & NUCLEAR 8 / 46 = 0.174 2016 Q1 T1 1.723 2016 Inorganic Chemistry 2016 Q1 Physical and Theoretical Chemistry 2016 Q1 Organic Chemistry 2016 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Díez, J.
