Oligoarylenes with three or four aromatic rings, bearing two S-acetylated mercaptomethyl groups in 1,3 position on one end of the polyaromatic system and presenting various functionalities on the other terminal ring, have been synthesized by the Suzuki−Miyaura cross-coupling reaction. The use of palladium complexes with a Buchwald's phosphine as ligand allowed us to perform this coupling reaction also
通过Suzuki-Miyaura交叉偶联反应合成了具有三个或四个芳环的寡亚芳基,在聚芳族系统的一个末端带有1,3位的两个S-乙酰化巯基甲基基团,而在另一个末端环上具有多种官能团。与布赫瓦尔德膦作为
配体的
钯配合物的使用使我们也可以在芳族卤化物上被苄基S-乙酰基保护的官能团的存在下进行这种偶联反应。所获得的低聚亚芳基是在
金属基材上产生自组装单层的潜在新候选物。
