incorporation of iodo, an important functionality for transition-metal-catalyzed cross-coupling reactions. In the case of sensitive aromatics, the addition of some donor solvent like diethyl ether proved effective in suppressing side reactions through electrophilic aromatic iodination.
描述了通过铃木(Suzuki)交叉偶联有效合成第一代和第二代芳基/烷基型非极性树突的方法。树突带有一个或两个苄基保护的羟烷基/末端。芳基三甲基硅烷与碘氯化物的碘去甲硅烷基化反应用作掺入碘的工具,碘是过渡金属催化的交叉偶联反应的重要功能。对于敏感的芳烃,事实证明添加一些供体溶剂(如乙醚)可有效抑制亲电子碘化副反应。
