Efficient annulation of vic-diborylalkenes and -arenes with vic-bromo(bromomethyl)arenes has been achieved, using Pd(PPh3)4 as a catalyst in the presence of Cs2CO3 and water in THF at 60 ËC, giving rise to the corresponding indene and fluorene derivatives in good to high yields.
已实现对vic-二硼烯和vic-芳烃与vic-溴(溴甲基)芳烃的高效环化反应,使用Pd(PPh3)4作为催化剂,在Cs2CO3和水的存在下,于THF中在60℃条件下进行,得到相应的茚和芴衍生物,产率良好至高。
