  硒催化的邻硝基甲苯分子内原子和氧化还原经济转化为邻氨基苯甲酸

  摘要：

  邻氨基苯甲酸（AAs）是用于制药，农用化学品，染料，香料等的重要基础化学品。获得AA总是涉及多余的步骤。本文中，我们证明了一种直接的策略即可将丰富的邻硝基甲苯转化为具有生物学和药学意义的AA，而无需任何额外的还原剂，氧化剂和保护基。在该转化中可以容许各种敏感基团，例如卤素，硫化物，醛，吡啶，喹啉等。通过几乎定量的硒回收，可以有效地实现一百克规模的操作。进一步的机理研究和DFT计算揭示了拟议的原子交换过程以及硒物种的关键作用。

  具有吸电子取代基的芳烃催化亲电卤化

  摘要：

  芳烃的亲电卤化可能是制备芳基卤化物的最简单方法，芳基卤化物是农用化学品、材料和药物中的重要结构基序。然而，芳烃的亲核性被吸电子取代基削弱，其亲电子卤化反应通常需要苛刻的条件，导致底物范围和应用受到限制。因此，在温和条件下卤化含有吸电子基团（EWGs）和复杂生物活性化合物的芳烃一直是一个长期的挑战。在此，我们描述了在温和条件下具有吸电子取代基的芳烃的 Brønsted 酸催化卤化，为芳基卤化物提供了一种有效的方案。布朗斯台德酸与质子溶剂 1,1,1,3,3 的氢键，
