  A series of sterically hindered (methoxylated) polychlorinated biphenyl derivatives were synthesized using the Suzuki and the Ullmann coupling reactions. The Suzuki coupling with Pd(dba)2/2-dicyclohexylphosphino-2′,6′-dimethoxybiphenyl (DPDB) gave better yields (65-98%) compared to the classic Ullmann coupling reaction (20-38%). Despite the reactive catalyst system, no significant coupling with aromatic

  使用 Suzuki 和 Ullmann 偶联反应合成了一系列空间位阻（甲氧基化）多氯联苯衍生物。与经典的 Ullmann 偶联反应 (20-38%) 相比，Suzuki 与 Pd(dba) 2 /2-二环己基膦基-2',6'-二甲氧基联苯 (DPDB) 的偶联产生更好的产率 (65-98%)。尽管有反应性催化剂体系，但没有观察到与芳族氯取代基的显着偶联。四种 PCB 衍生物的晶体结构分析显示固态二面角范围为 69.7° 至 81.0°，这表明这些高度邻位取代的 PCB 衍生物具有一定的构象灵活性。 联芳基 - 钯 - Suzuki 交叉耦合 - Ullmann 交叉耦合 - 二面角
