  甲醇和喹喔啉（或苯并噻唑）之间的多重键裂解和形成：甲醛二甲基缩醛的合成

  摘要：

  已经实现了由AK 2 S 2 O 8介导的喹喔啉（或苯并噻唑）与甲醇的直接交叉偶联反应，从而生成了2-喹喔啉基（或2-苯并噻唑基）甲醛二甲基乙缩醛。在酸性条件下，2-喹喔啉基甲醛二甲基乙缩醛易于以良好或优异的收率转化成2-喹喔啉基甲醛。初步的机理研究表明，该反应是通过多重键裂解和甲醇与N-杂环之间的形成而进行的，涉及双氧参与的自由基过程。该方法可以通过简单的N的交叉偶联直接合成各种2-喹喔啉基（或2-苯并噻唑基）甲醛二甲基乙缩醛。-在无醛，无酸和无过渡金属的条件下，杂环C–H键和甲醇。

  2-quinoxalinyl (or 2-benzothiazolyl) carbaldehyde dimethyl acetals has been achieved. 2-Quinoxalinyl carbaldehyde dimethyl acetals were readily converted into 2-quinoxalinyl carbaldehydes in good to excellent yields under acidic conditions. Preliminary mechanistic studies suggest that the reaction proceeds via multifold bond cleavage and formation between methanol and N-heterocycles involving a dioxygen-participated
