A stable gold(i)-enyne species obtained by alkyne carboauration in a complex rearrangement 2017 An unprecedented tetranuclear gold derivative with unusual gold-enyne moieties is prepared by a mild and neat rearrangement of a dinuclear gold complex with a bridging bis(diphenylphosphino)alkyne and terminal alkynyl ligands. The complex originates as a consequence of an intramolecular addition of the AuCCTol fragment to the internal diphosphine triple bond Ph2PCCPPh2. The crystal structure of the tetranuclear complex shows a dinuclear metallacycle with a very short Au¿Au bond interaction and bridging phosphino-enyne ligands. This disposition clearly stabilises the elusive vinyl gold species omnipresent as intermediates in gold-catalysed reactions. info:eu-repo/semantics/closedAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 6.29 2017 CHEMISTRY, MULTIDISCIPLINARY 28 / 169 = 0.166 2017 Q1 T1 2.555 2017 Catalysis 2017 Q1 Ceramics and Composites 2017 Q1 Chemistry (miscellaneous) 2017 Q1 Surfaces, Coatings and Films 2017 Q1 Materials Chemistry 2017 Q1 Metals and Alloys 2017 Q1 Electronic, Optical and Magnetic Materials 2017 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Blanco, M.C.
