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(C
所述arylsilver衍生物AGR(R = C 6 ˚F 5,2,4,6--C 6 ˚F 3 ħ 2或C 6氯5)与chlorogold反应(I)的前体[AUCL(THT),AUCL(PPH 3),ClAu (dppm)AuCl(tht =四氢噻吩,dppm =双(二苯基膦基)甲烷],得到的芳基金配合物收率良好。在金前体处于较高氧化态的情况下,AgC 6 Cl 5会导致金(I)还原或生成没有反应,而AgC 6 F 5和AgC 6 F 3 H 2生成金(II)络合物(R 2Au(dppm)AuR 2)或金(III)络合物[Au(C 6 F 3 H 2)(C 6 F 5)2(PPh 3);Au(C 6 F 3 H 2)2(C 6 F 5)(tht); Au(C 6 F 5)3(tht); Au(C 6 F 3 H 2)3(tht)]。
