Résumé

The arylsilver derivatives AgR (R = C6F5, 2,4,6-C6F3H2 or C6Cl5) react with chlorogold(I) precursors [AuCl(tht), AuCl(PPh3), ClAu(dppm)AuCl (tht = tetrahydrothiophene, dppm = bis(diphenylphosphino)methane], 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 [Au(C6F3H2)(C6F5)2(PPh3); Au(C6F3H2)2(C6F5)(tht); Au(C6F5)3(tht); Au(C6F3H2)3(tht)]. © 1988.
