, p. 235 - 247 (1992)
The reaction of (R=C6F5 or 2,4,6-C6F3H2) with Au(ONO2)PPh3, ClO4 or ClO4 (tht=tetrahydrothiophene) leads to neutral 1 or monocationic derivatives ClO4 .Complexes 3 and 5 react with anionic or neutral reagents, giving new neutral or monocationic gold(II) compounds.The structure of ClO4*0.5CH2Cl2 (2) was determined by single-crystal X-ray diffraction.Crystals are triclinic, space group P, a=12.468(2), b=13.493(2), c=18.283(3) Angstroem, α=108.13(1) deg, β=91.09(1) deg, γ=111.95(1) deg and Z=2.Final R is 0.0376 forb4906 unique observed reflections.The Au-Au bond length is 2.6612(8) Angstroem.

The reactions of [Ag(NH=CMe2)2]ClO4 with cis-[PtCl2L2] in a 1:1 molar ratio give cis-[PtCl(NH=CMe2)(PPh3)2]ClO4 (1cis) or cis-[PtCl(NH=CMe2)2(dmso)]ClO4 (2), and in 2:1 molar ratio, they produce [Pt(NH=CMe2)2L 2](ClO4)2 [L = PPh3 (3), L 2 = tbbpy = 4,4′-di-tert-butyl-2,2′-dipyridyl (4)]. Complex 2 reacts with PPh3 (1:2) to give trans-[PtCl(NH=CMe 2)(PPh3)2]ClO4 (1trans). The two-step reaction of cis-[PtCl2(dmso)2], [Au(NH=CMe 2)(PPh3)]ClO4, and PPh3 (1:1:1) gives [SP-4-3]-[PtCl(NH=CMe2)(dmso)(PPh3)]ClO4 (5). The reactions of complexes 2 and 4 with PhICl2 give the Pt(IV) derivatives [OC-6-13]-[PtCl3(NH=CMe2)2(dmso)] ClO4 (6) and [OC-6-13]-[PtCl2(NH=CMe2) 2(dtbbpy)](ClO4)2 (7), respectively. Complexes 1cis and 1trans react with NaH and [AuCl(PPh3)] (1:10:1.2) to give cis- and trans-[PtCl{μ-N(AuPPh3)=CMe2}(PPh 3)2]ClO4 (8cis and 8trans), respectively. The crystal structures of 4·0.5Et2O·0.5Me2CO and 6 have been determined; both exhibit pseudosymmetry.
(Polyhalophenyl)silver(I) complexes as arylating agents: Crystal structure of ClO4
Uson, Rafael,Laguna, Antonio,Fernandez, Eduardo J.,Mendia, Aranzazu,Jones, Peter G.
, p. 129 - 138 (2007/10/02)
The arylsilver derivatives AgR (R=C6F5, 2,4,6-C6F3H2 or C6Cl5) react with chlorogold(I) precursors , to give the corresponding arylgold complexes in good yield.With gold precursors in higher oxidation state, AgC6Cl5 either causes reduction to gold(I) or gives no reaction, whereas AgC6F5 and AgC6F3H2 lead to gold(II) complexes (R2Au(dppm)AuR2) or gold(III) complexes .
Mononuclear gold(I) and heteronuclear gold(I)-palladium(II) bibenzimidazolate complexes with new coordination modes of the ligand
Uson,Gimeno,Fornies,Martinez,Fernandez
, p. 91 - 96 (2008/10/08)
Metathetic reactions of gold(I) halide complexes and the potassium salt of 2,2′-bibenzimidazol afford binuclear bibenzimidazolate gold(I) complexes with the general formula {Au2L2}(μ-BiBzIm) L = PPh3, PBun3, P(OMe)3; L2 = 1,1-bis(diphenylphosphine)-methane (dppm), 1,2-bis(diphenylphosphine)ethane (dppe). These complexes are Lewis bases and can be used as precursors for the synthesis of tri and tetranuclear cationic gold(I) complexes, or trinuclear gold(I) and palladium(II) complexes where the bibenzimidazolate anion is acting as bridging tetranuclear ligand. An hexanuclear gold(I)-palladium(II) complex is also described.
GOLD(I) AND PLATINUM(II) AZOLATES AS LIGANDS IN CATIONIC RHODIUM(I) COMPLEXES
Uson, R.,Oro, L. A.,Ciriano, M. A.,Pinillos, M. T.,Cabeza, J. A.
, p. 249 - 256 (2007/10/02)
Several cationic heterometallic rhodium complexes have been obtained by using the complexes ImAuPPh3 or (az)2Pt(dpe) (az=imidazolate (Im) or pyrazolate (Pz) anions) as ligands.Attempts to prepare rhodium(I)-gold(I) derivatives containing pyrazolate-bridging ligands proved unsuccessful, rearrangements giving the complexes 2 and ClO4, ClO4 or AuClPPh3 as end-products.
