a promising approach for the conversion of allylic difluoro-homoallylic alcohols into trisubstituted monofluoroalkenes in good yields with excellent stereoselectivity. The mechanism study shows that C–F bond activation via oxidative addition is involved and PPh3 is responsible for the excellent stereoselectivity.
铑通过氧化加成催化的烯丙基CF键活化是将烯丙基二氟-均烯丙基醇以良好的产率和良好的立体选择性转化为三取代的单氟烯烃的一种有前途的方法。机理研究表明,涉及通过氧化加成作用的CF键活化,PPh 3负责出色的立体选择性。
