We have synthesized the gold(III) complex Au(C6F5)3(PPh2CCH) (1), containing an acetylene moiety. Reactions with sodium alkoxides lead chemoselectively and regioselectively to gold(III) complexes containing the new ligand (2-alkoxyethenyl)diphenylphosphine or (2,2-dialkoxyethyl)diphenylphosphine, via a single or double alcohol addition to the acetylenephosphine fragment. Reaction of complex 1 with gold(I) or silver(I) acetylacetonato derivatives affords di-, tri-, or tetranuclear alkynylphosphino complexes, namely AuIII(C6F5)3 (PPh2CC)-MI(PPh3) (M = Au, Ag), {AuIII(C6F5)3 (PPh2CC)}2AuI and {AuIII(C6F5)3(PPh2CC) AuI}2 (μ-PPh2CH2CH2 PPh2). The crystal structures of Au(C6F5)3(PPh2CH2 CH(OMe)2) and AuIII (C6F5)3(PPh2CC)AuI (PPh3) have been determined by X-ray diffraction studies. Luminescence studies in the solid state show that only the tetranuclear derivative is luminescent at room temperature.
