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