A new strategy for Rh(I)-catalyzed [2+2+2] cycloadditions of 1,6-diynes with potassium (Z)-(2-bromovinyl)trifluoroborate as the third two-atom unit has been realized, which provides a facile entry to polysubstituented benzene derivatives.
以 (Z)-(2-bromovinyl)trifluoroborate
钾作为第三个双原子单元,实现了 Rh(I)- 催化 1,6- 二炔的 [2+2+2] 环加成反应的新策略,为多取代基苯衍
生物提供了简便的入口。
