environmentally benign manner. A novel C–OH bond cleavage method was found to be crucial for this practical protocol. A variety of alkenes and allylic alcohols equipped with wide-spectrum functional groups can be successfully incorporated into the desired cross-coupling, affording 1,4-dienes with moderate to excellent yields and high stereo- and regioselectivity.
我们通过结合市售的 Ca(NTf 2 )PF 6和 Pd(PPh 3 ) 4设计了一种协同催化系统,以环境友好的方式解决烯基 sp 2 C-H 键的脱
水烯丙基化问题。发现一种新的 C-OH 键裂解方法对于该实用方案至关重要。各种具有广谱官能团的烯烃和
烯丙醇可以成功地结合到所需的交叉偶联中,从而提供具有中等至优异产率和高立体选择性和区域选择性的 1,4-二烯。
