6-dipent-3-ylphenyl)imidazol-2-ylidene]palladium(II)} yields triphenylsilyl-protected anilines. These triphenylsilyl protected anilines can be isolated, alkylated without over-alkylation, and the protecting group can be removed under mild acidic conditions or in the presence of fluoride to afford the secondary aniline product.
使用 Pd-PEPPSI-IPentCl dichloro(3-chloropyridyl)[4,5-dichloro-1,3-bis(2,6-dipent-3-ylphenyl)imidazol-2-ylidene] 钯偶联 Ph3SiNH2 与芳基卤化物(II)} 生成三苯基甲硅烷基保护的苯胺。这些三苯基甲硅烷基保护的苯胺可以被分离、烷基化而不会过度烷基化,并且可以在温和的酸性条件下或在氟化物存在下去除保护基团,得到二级苯胺产物。
