  Visible Light-Promoted Photocatalytic C-5 Carboxylation of 8-Aminoquinoline Amides and Sulfonamides via a Single Electron Transfer Pathway

  摘要：

  An efficient photocatalytic method was developed for the remote C5-H bond carboxylation of 8-aminoquinoline amide and sulfonamide derivatives. This methodology uses in situ generated ^•CBr₃ radical as a carboxylation agent with alcohol and is further extended to a variety of arenes and heteroarenes to synthesize the desired carboxylated product in moderate-to-good yields. The reaction proceeding through a single electron transfer pathway was established by a control experiment, and a butylated hydroxytoluene-trapped aryl radical cation intermediate in high-resolution mass spectrometry was identified.

  non‐emissive behavior has been related to the low electrochemical energy gaps and rationalized on the basis of theoretical calculations (DFT analysis) that predict low S0←T1 energy values. Moreover, the RuII complexes, despite being non‐emissive, display excellent activities in the selective photocatalytic transformation of benzylamines into the corresponding imines. The presence of an electron‐withdrawing

  制备了五种新的带有N-（芳基磺酰基）-8-氨基喹啉酸酯配体的Ru II聚吡啶基配合物及其双环金属化的Ir III同源物中的三个，并将其用作光催化剂（PC），用于苄胺与O 2的光氧化。尤其是，新的Ru II络合物没有光致发光，而是有效地收集可见光，并且在蓝光照射下在溶液中非常稳定。它们的非发射行为与较低的电化学能隙有关，并根据预测低S 0 ←T 1能量值的理论计算（DFT分析）进行了合理化。而且，汝II配合物尽管不发散，但在苄胺向相应的亚胺的选择性光催化转化中表现出出色的活性。N-（芳基磺酰基）-8-酰氨基喹啉酸酯配体的芳环上存在一个吸电子基团（-CF3），可提高相应光催化剂的光催化活性。此外，所有实验证据，包括瞬态吸收光谱法测量均表明，单重态氧是实际的氧化剂。Ir III类似物的光敏性更高，因此光敏剂（PS）的效率也较低。
