repetitive two-step method for oligoarene synthesis, based on Negishi cross-coupling of zinciophenoxides or zinciopyridinoxides with aryl triflates and subsequent triflation of the hydroxy group, was developed. Reaction conditions were optimized for the preparation of the arylzinc compounds and the palladium-catalyzed cross-coupling step.
开发了一种新颖的重复性两步法合成低聚芳烃的方法,该方法基于Negishi将氧化锌苯酚或氧化锌吡啶氧化物与芳基三氟甲磺酸酯交叉偶联,然后对羟基进行三氟甲磺酸酯化。优化了反应条件以制备芳基锌化合物和钯催化的交叉偶联步骤。
