synthesis of boronic acids has greatly facilitated the two-step, one-pot borylation/Suzuki cross-coupling reaction between aryl and heteroaryl halides. With use of Buchwald’s second-generation XPhos preformed catalyst, high yields of cross-coupled products were obtained for most substrates. The method also allows an efficient two-step, one-pot synthesis, providing access to three distinct cross-coupled
使用双硼酸直接合成硼酸极大地促进了芳基和杂芳基卤化物之间的两步、一锅硼化/铃木交叉偶联反应。使用 Buchwald 的第二代 XPhos 预制催化剂,大多数底物都获得了高产率的交叉偶联产物。该方法还允许高效的两步一锅合成,在柱层析后提供三种不同的交叉偶联产物。该方法还提供了获得四芳基化合物的快速方便的途径。
