the job: 1,6‐Difunctionalized alkyl units, which are traditionally hard to access, have been successfully obtained through a reductive cross‐coupling of activated alkenes catalyzed by TiIII. A plausible reaction mechanism that proceeds through redox umpolung of the enone is briefly discussed (see scheme, Cp=cyclopentadiene).
钛可以做到这一点:通过Ti III催化的活化烯烃的还原性交叉偶联,成功地获得了传统上难以获得的1,6-双官能化烷基单元。简要讨论了通过烯酮的氧化还原物质进行的可能的反应机理(参见方案,Cp =
环戊二烯)。
