Experimental data, including an unusual high-field chemical shift in the 1H and 13C NMR spectra, and DFT theoretical calculations support the proposal that the copper−olefin linkage is mainly sustained by σ-donation, lacking a substantial degree of π-back-donation}, organization = {We thank the MICINN (Proyecto CTQ2008−00042BQU, CTQ2008-06866-CO2-02/BQU and Consolider Ingenio 2010 grant CSD2006-0003), the Junta de Andalucía (Proyecto P07-FQM-02794), and the ICIQ Foundation for financial support.
