A series of 1-arylnaphthalenes and 1,8-diarylnaphthalenes were synthesized by the Suzuki–Miyaura cross-coupling methodology showing significant differentiation in the yields and selectivity between aryl rings with electron donating (higher yields), and electron withdrawing substituents (lower yields). These results strongly support the relation between the nucleophilicity of the boronate complex and
Suzuki-Miyaura交叉偶联方法合成了一系列1-芳基萘和1,8-二芳基萘,显示出在带电子给体(较高的产率)和吸电子取代基(较低的产率)的芳环之间,产率和选择性存在显着差异。 。这些结果强烈支持硼酸酯络合物的亲核性与其反应性之间的关系,并强调了重金属化步骤在该交叉偶联反应的总效率中的重要性。用非对称的1,8-二芳基萘获得的结果表明,与1,8-二溴萘的单芳基化相比,已芳基化的物种(1-芳基-8-溴萘的中间体)的芳基化更容易。
