Catalyzed by Pd(II)/p-BQ, a tandem cycloisomerization and oxidation of arylvinylcyclopropenes took place smoothly to produce methyleneindene derivatives stereoselectively in moderate to excellent yields, affording an unusual example of solo addition by p-hydroquinone generated by oxidation of Pd(0) to Pd(II) along with the formation of a new C−O bond.
加入Pd(II)催化的/ p -bq,串联和环异构的arylvinylcyclopropenes氧化发生顺利以产生methyleneindene衍生物立体选择性地在中等至良好的产率,得到独奏除了通过的一个不寻常的例子p的Pd,氧化产生的氢醌(0 )形成Pd(II),同时形成新的C-O键。
