Abstract

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.
