Abstract

The reaction between [AuCl(tht)] (tht = tetrahydrothiophene) and the ylide Ph₃P=CHC(O)NMe₂ gives [AuCl{CH(PPh₃)C(O)NMe₂}] 1, which reacts with chlorine to gives [AuCl₃{CH(PPh₃)C(O)NMe₂}] 2 and with the same ylide and NaClO₄ to form [Au{CH(PPh₃)C(O)NMe₂}₂]ClO₄ 3. The analogous silver complex [Ag{CH(PPh₃)C(O)NMe₂}₂]ClO₄ 4 is obtained by the reaction of AgClO₄ with the ylide in molar ratio 1:2. The phosphonium salt [Ph₃PCH₂C(O)NMe₂]ClO₄ reacts with [Au(acac)(PPh₃)] (acac = acetylacetonate) to gives [Au{CH(PPh₃)C(O)NMe₂}(PPh₃)]ClO₄ 5 or [(AuPPh₃)₂{μ-C(PPh₃)C(O)NMe ₂}]ClO₄ 6 depending on the reaction conditions. The structure of 6 was confirmed by an X-ray diffraction study at -95 °C [space group P1, a = 11.572(3), b = 11.836(3), c = 21.627(7) Å, α = 78.29(2), β = 87.19(2), γ = 75.65(2)°, R = 0.076]; the Au⋯Au bond length is 2.938(1) Å.
