Resumen
Vinylidenebisfdiphenylphosphane) reacts with gold(I) or gold(III) compounds to give dinuclear {[{Au(C6F5)]2{(PPh2)2C= CH2J] or Au(PPh2C(=CH2)Ph2P)]2(ClO4) 2) or mononuclear complexes ([Au(C6F5)3{PPh2C(=CH2)Ph 2PJ]}, respectively. The latter reacts with gold(I) or silver(I) compounds to afford dinuclear[Au(C6Fs)3|PPh2C(=CH 2)Ph2P)AuX], X = Cl or C6FS) or trinuclear species {[{Au(C6Fs)3{PPh2C{=CH2)Ph 2Pl)2M]ClO4, M = Au or AgJ. No addition of nucleophiles to the C=C double bond is observed in these complexes, which contain the diphosphane acting as bridging or monodentate ligand. (SPPri2)2C= CH2 reacts with AgCIO4 to give [Ag{SPPh2C(=CH2)Ph2PS)]2(C1O4) 2 or [Ag{PPh2C(=CH2)Ph2P)2]ClO4. The crystal structure of [Au(C6Fs)3{PPh2C(=CH2)Ph2P)Au(C 6Fs)] has been established by X-ray crystallography, and confirms the expected square planar and linear geometry for the Aum and Au1 centres, respectively. © WILEY-VCH Verlag GmbH,.
