(Ar–CO–C[triple bond, length as m-dash]C)(PEt3)Au and (Ar–C[triple bond, length as m-dash]C)(PEt3)Au complexes bearing pyrenyl and ferrocenyl groups: synthesis, structure, and luminescence properties

Abstract

Two types of (acetylide)(triethylphosphine)gold(I) complexes ArCOC[triple bond, length as m-dash]CAuPEt3 (1a and 1b) and ArC[triple bond, length as m-dash]CAuPEt3 (2a and 2b) bearing Ar = pyren-1-yl or ferrocenyl group were synthesized and the effect of a carbonyl moiety on the structure, propensity to ligand scrambling in solution and luminescence properties were investigated. We found that the complexes bearing acetylenic ketone-derived ligands underwent ligand scrambling in solution to afford mixtures of ArCOC[triple bond, length as m-dash]CAuPEt3 and [(ArCOC[triple bond, length as m-dash]C)2Au][Au(PEt3)2]+. The latter complexes were isolated and their structures were confirmed by single crystal X-ray diffraction studies. The aurophilic interaction of Au⋯Au in these complexes resulted in the formation of wire-like structures.
