Abstract
Highly efficient and simple cross-coupling reactions of 2-bromobenzo[]furans with alkenylaluminum reagents for the synthesis of 2-alkenylbenzo[]furan derivatives using PdCl (3 mol%)/XantPhos (6 mol%) as catalyst are reported. Excellent yields (up to 97%) were obtained for a wide range of substrates at 80 °C for 4 h in DCE.
摘要
报道了使用PdCl（3摩尔%）/XantPhos（6摩尔%）作为催化剂，2-溴苯并呋喃与烯基铝试剂进行高效且简单的交叉偶联反应，用于合成2-烯基苯并呋喃衍生物。在80℃下于二氯乙烷中反应4小时，对于多种底物都获得了优异的产率（高达97%）。
