Resumen
The reaction between the chalcogenide derivatives [Au(C6F5)3(PPh2CH 2PPh2E)] (E = S, O) and [Au(acac)PPh3] or [Au(TfO)PPh3] leads to the dinuclear compounds [Au(C6F5)3{PPh2CH(AuPPh 3)PPh2E}] (E = S, O) or [Au(C6F5)3{PPh2CH 2PPh2(SAuPPh3)}], respectively. When the phosphine disulphide complex [Au(C6F5)3(SPPh2CH 2PPh2S)] is employed, the reaction with [Au(acac)PPh3] promotes the double substitution of the methylenic protons. The reaction of [Au(acac)L] (L = PPh3, AsPh3) with the six-membered auracycle [Au(C6F5)2{(SPPh2)2CH 2}]ClO4 leads to the double substitution of both methylenic protons by [AuL]+ fragments, keeping the auracycle intact. The crystal structure of one such product, [Au(C6F5)2{(SPPh2) 2C(AuAsPh3)2}]ClO4 has been established by X-ray diffraction studies. Starting from the methanide derivative [Au(C6F5)2(SPPh2CHPPh 2S)], the reaction with [Au(acac)PPh3] leads to the synthesis of the four-membered ring methanide [Au(C6F5)2{SPPh2C(AuPPh 3)PPh2S}] © 1998 Elsevier Science Ltd.
