Palladium-catalyzed cross-coupling reactions of functionalized bromofurans with triarylbismuths have been described for the atom-economic synthesis of functionalized arylfuran systems. The coupling reactions using triarylbismuths with various 2-bromofurans and 2,5-dibromofuran underwent smoothly to afford the corresponding 2-arylfurans and 2,5-diarylfurans in high yields in a short reaction time (one
钯催化的功能化溴呋喃与三芳基铋的交叉偶联反应已被描述用于功能化芳基呋喃系统的原子经济合成。使用三芳基铋与各种 2-溴呋喃和 2,5-二溴呋喃的偶联反应顺利进行,在短反应时间(1 小时)内以高产率得到相应的 2-芳基呋喃和 2,5-二芳基呋喃。
