[NBu4][Ag(C6F5)2] or [Ag(C6F5)] act as arylating ligands able to transfer two or one pentafluorophenyl groups to [Tl(C6F5)2Cl] leading to [NBu4][Tl(C6F5)4] (1) and [Tl(C6F5)3(diox)] (diox=1,4 dioxane) (2) in an improved synthesis, the latter being a starting material for the synthesis of [Tl(C6F5)3(OPPh3)] (3) and [Tl(C6F5)3(PPh3)] (4). However, [Ag(C6F5)L] does not transfer the pentafluorophenyl group
[NBu 4 ] [Ag(C 6 F 5)2 ]或[Ag(C 6 F 5)]充当芳基化配体,能够将两个或一个五氟苯基基团转移至[Tl(C 6 F 5)2 Cl],从而导致[NBu 4 ] [Tl(C 6 F 5)4 ](1)和[Tl(C 6 F 5)3(diox)](diox = 1,4二恶烷)(2),其为改进的合成合成[Tl(C 6 F 5)3的原料(OPPh 3)](3)和[Tl(C 6 F 5)3(PPh 3)](4)。但是,[Ag(C 6 F 5)L]与[Tl(C 6 F 5)2 Cl]和络合物[Tl(C 6 F 5)2 Cl(py)] 2反应时不转移五氟苯基。(5),[Tl(C 6 F 5)2 Cl(OPPh 3)] 2(6)和[Tl(C 6 F获得5)2(OdppmO)2 ] [Tl(C 6 F 5)2 Cl 2 ](7)作为主要产物,通过在[Tl(C)中添加中性配体可以更好的收率获得6
