Silyloxyarenes were utilized as electrophilic coupling partners with amines in the synthesis of aniline derivatives. A diverse range of amine substrates were used, including cyclic or acyclic secondary amines, secondary anilines, and sterically hindered primary anilines. Additionally, a range of sterically hindered and unhindered primary aliphatic amines were employed, which have previously been challenging with
在苯胺衍生物的合成中,甲硅烷氧基芳烃被用作与胺的亲电子偶联伴侣。使用了多种胺底物,包括环状或无环仲胺,仲苯胺和位阻伯苯胺。另外,使用了一系列空间受阻和不受阻碍的伯脂族伯胺,这些伯胺以前对其他种类的芳基醚亲电试剂具有挑战性。举例说明了甲硅烷基氧芳烃与芳基甲基醚的正交偶联,其中两个C-O亲电试剂之间的选择性由配体控制确定,从而使任一亲电试剂实现互补和选择性的后期多样化。最后,
