  摘要：

  本文评估了5-芳基-2-吡啶基恶唑主链，以设计一或两个光子吸收后的供体-受体荧光pH探针。可以容易地以高收率容易地获得母体荧光团以及可用于标记生物分子的衍生物。这些分子在近紫外范围内显示出大的单光子吸收，并具有覆盖整个可见域的强荧光发射。5-芳基-2-吡啶基恶唑衍生物还具有明显的截面，用于吸收两个光子。吡啶质子化后，在单光子和双光子激发后的吸收光谱中以及发射光谱中观察到了大的位移。此功能用于测量所研究化合物的pK（a），范围在2至8之间。在大多数所研究的衍生物中，pK（a）随光激发而增加，并且在激发态的寿命期间发生质子交换，如相位调制荧光法分析所示。建议使用几种5-芳基-2-吡啶基恶唑衍生物作为有效探针，以依赖于荧光发射的比例法可靠地测量水溶液的pH。

• Lewis Basic Salt-Promoted Organosilane Coupling Reactions with Aromatic Electrophiles
  作者：Tyler W. Reidl、Jeffrey S. Bandar

  日期：2021.8.11

  Lewis basic salts promote benzyltrimethylsilane coupling with (hetero)aryl nitriles, sulfones, and chlorides as a new route to 1,1-diarylalkanes. This method combines the substrate modularity and selectivity characteristic of cross-coupling with the practicality of a base-promoted protocol. In addition, a Lewis base strategy enables a complementary scope to existing methods, employs stable and easily

  methodologies exist for amine synthesis, but the direct synthesis of primary amines with a fully substituted α carbon center is an underdeveloped area. We report a method which utilizes photoredox catalysis to couple readily available O-benzoyl oximes with cyanoarenes to synthesize primary amines with fully substituted α-carbons. We also demonstrate that this method enables the synthesis of amines with α-trifluoromethyl
