  摘要：

  通过 9-硼双环 [3.3.1] 壬烷的 1,2-加成，色素被区域选择性地还原为 2H-1-苯并吡喃。虽然过渡金属配合物对反应没有催化作用，但仅通过使用氯化钯（II），才能在相似程度上获得2H-1-苯并吡喃和二氢-1-苯并吡喃。此外，使用其他有机硼烷还原色酮不会产生 2H-1-苯并吡喃，而是通过仅还原烯烃部分产生色酮。

  一种有效的TBHP / TBAI介导的协议，可通过氧化CC键从苯并吡喃-4-酮合成4 H-铬-4-酮

  摘要：

  摘要已经开发了一种无过渡金属且高效的TBHP / TBAI介导的方案，用于通过氧化C-C键形成从苯并吡喃-4-酮合成4 H -chromen-4-酮。它在催化量的碘化四丁基铵和氧化剂叔丁基过氧化氢（TBHP，癸烷中的5-6 M）存在下进行，以良好的收率获得了相应的产物。此外，已经观察到TBHP的浓度增加到30mol％大大增加了4 H的收率。-chromen-4-ones，进一步增加将导致产率降低。该反应的机理涉及最初生成叔丁氧基自由基，其通过氧化单电子转化被转化为碘代色烷-4-酮。之后，将碘化氢从碘代chroman-4-one中除去，得到所需的产物，即4 H -chromen-4-ones。此外，这是通过脱氢反应由n -Bu 4 NI / TBHP介导的C–C键的罕见例子。 图形摘要
