  供体-受体Stenhouse加合物的光致异构化途径上的亮点

  摘要：

  供体-受体Stenhouse加合物（DASA）是负性光致变色材料，在各种应用中都具有广阔的前景。优化其开关特性的关键是对光开关机制的详细了解，但目前尚无。在这里，我们描述了DASA光开关及其主要中间体的光化步骤，并结合了超快可见光和IR泵浦光谱仪和TD-DFT计算进行了研究。将时间分辨的红外光谱与DFT计算进行比较，可以清楚地确定中间体的结构，从而确认光吸收会诱导顺序反应路径，其中C 2 –C 3的Z–E光异构化随后是围绕C的旋转3 –C4和随后的热环化步骤。第一代和第二代DASA在氯化溶剂中具有共同的光异构化机制，在激发态的动力学和寿命方面存在显着差异。第二代DASA的光生中间体在低温下光聚集，并用时间分辨光谱进行探测，证明了异构化过程的光可逆性。综上所述，这些结果在分子水平上提供了DASA异构化途径的详细描述。

  A metal‐free aerobic oxidative C–H sulfenylation of aryl‐fused cyclic amines with various thiols was developed with excellent functional compatibility. While flavin I catalyzed the C–H sulfenylation of indolines to afford 3‐sulfenylindoles, flavin II enabled transformations resulting in substitution at the position para to the N atom on the aryl ring to obtain 6‐sulfenylquinolines.

  The dehydrogenative coupling of indolines with alcohols catalyzed by an iridium complex has been achieved to afford both N- and C3-alkylated indoles selectively, by simply changing the addition time of a base additive. The iridacycle catalyst plays multiple roles in these reactions, which dehydrogenates both amines and alcohols and catalyzes the coupling reactions. Mechanistic studies reveal that a
