Abstract

The reaction of [Au(C6F5)2(acac)] (acac = acetylacetonate) with (Ph2P)3CH led to [Au(C6F5)2-{(Ph2P) 2CPPh2}] 1, which reacts further with [AuX(tht)] (X = Cl or C6F5, tht = tetrahydrothiophene), [Au(tht)2]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.
