the changes: The direct cross‐coupling of electron‐deficient 1,4‐benzoquinone or its derivatives with electron‐rich alkyl vinyl ethers proceeds in a tandem manner to produce substituted benzene rings with good selectivity and in good to excellent yields (see scheme). The reaction has the potential for the rapid synthesis of diverse substituted benzene rings as it is not limited by substituent effects
应对变化:缺电子的1,4-苯醌或其衍生物与富电子的烷基乙烯基醚的直接交叉偶联以串联方式进行,以产生具有良好选择性和良好至极佳收率的取代苯环(请参见方案) )。该反应具有快速合成各种取代的苯环的潜力,因为它不受取代基作用的限制。
