经过大量的条件筛选和优化,最终确定以Pd(OAc)2作为催化剂,Xantphos作为配体,Cs2CO3作为碱,PhH为溶剂在蓝光和室温下反应12小时为最佳反应条件,反应以88%的分离收率获得所需的Heck产物2a,反/顺(E/Z)比为5:1。值得高兴的是,没有在该反应条件下观察到直接Heck产物(SP1)和加氢脱卤的产物(SP3),仅检测到6%的去...
Moderate to good yields of symmetrical biaryls were achieved under very mild conditions via homocoupling of arylboronic acids catalyzed by Pd(OAc) 2 under air without using ligand. And the reactions were performed in acetone/water ( v/ v = 1:1) at room temperature without giving side products...
