Article abstract of DOI:10.1039/DT9940003487

The reaction of (acac = acetylacetonate) with (Ph2P)3CH led to > 1, which reacts further with (X = Cl or C6F5, tht = tetrahydrothiophene), ClO4 or AgClO4 to give dinuclear <(F5C6)2Au<(Ph2P)2CPPh2>AuX> or trinuclear complexes <(Au(C6F5)2<(Ph2P)2CPPh2>>2M> (M = Au or Ag).Complex 1 reacted with gold(III) complexes to give dinuclear <(F5C6)2Au<(Ph2P)2CPPh2>Au(C6F5)2X> (X = Cl or C6F5) or trinuclear complexes <(Au(C6F5)2<(Ph2P)2CPPh2>>2Au(C6F5)2>.Complex 1 is protonated by reaction with HBF4.The structures of complex 1 and <(F5C6)2Au<(Ph2P)2CPPh2>AuCl> have been established by X-ray crystallography, confirming in the latter that the gold(I) centre is co-ordinated to the free phosphorus instead of the methanide C.
