| Abstract: | Neutral polyfluorophenyl complexes of the type RAuL and RAuL-LAuR and anionic complexes of the type AuR2]? (R = 2,3,5,6-C6F4H, 2,4,6-C,F3H2, 3,6-C6F2H3, 4-C6 FH4 or 3-CF3C,H4) are obtained by the reaction of ClAuL (L = PPh3, P(cyclohexyl)3, AsPh3 or tetrahydrothiophen; L-L = Ph2PCH2PPh2 or Ph2PCH2CH2PPPh2) with an organolithium derivative and/or the replacement of the initial ligands L by other mono- or bi-dentate ligands.The outcome of the reaction of AuR2]? with Au(PCy3)2]+ (Cy = cyclohexyl), depends on the nature of the ligand R; thus with R = 3,6-C6,F2H3 the product is Au(PCy3)2]AuR2], while with R = 2,4,6-C6F3H2, the product is Au(PCy3)(2,4,6-C6F3H2)]. |
