  咔唑催化剂与碳酸铯催化光催化还原烷基芳醚

  摘要：

  激活相对稳定的醚C-O键并将其转化为其他官能团的方法是理想的。醚的单电子还原是裂解C-O键的潜在途径。然而，由于烷基芳基醚的高度负氧化还原电势（E red <-2.6 V vs SCE），这种醚C–O键活化方式具有挑战性。在本文中，我们报告了使用咔唑基有机光催化剂（PC）的可见光诱导的烷基芳基醚C–O键的光催化裂解。苄基和非苄基芳基醚均经过C–O键裂解形成相应的苯酚产物。添加Cs 2 CO 3是有益的，特别是在使用NH咔唑PC的反应中。建议该反应通过从激发态咔唑到底物醚的单电子转移（SET）进行。N – H咔唑PC通过氢键与Cs 2 CO 3相互作用，这使得去质子辅助的电子转移机制得以运行。另外，路易斯酸性Cs阳离子与底物烷基芳基醚相互作用以活化它作为电子受体。咔唑的高还原能力与Cs 2 CO 3的有益作用相结合，使这种原本可怕的SET事件成为可能。

• Recyclable synthesis of mesityl iodonium(III) salts
  作者：Toshifumi Dohi、Takumi Hayashi、Shohei Ueda、Toshitaka Shoji、Keina Komiyama、Hitoshi Takeuchi、Yasuyuki Kita

  target mesityl iodonium(III) salts in good yields at room temperature with broad functional group tolerance. This C–H condensation strategy merits high para-regioselectivities during the diaryliodonium(III) salt formation, but the major limitation in the case of low-reactive aromatic substrates is byproduct formation resulting from the self-condensation of the nucleophilic mesitylene ring in MesI(OH)OTs

  氟代醇中高价碘化合物向芳烃的C–H缩合的有效方案已被用于可再生的均三碘鎓（III）盐的制备。在2,2,2-三氟乙醇中，可以适当提高[羟基（甲苯磺酰氧基）碘]间三甲苯（MesI（OH）OTs）和偏苯二甲酰二乙酸酯（MesI（OAc）2）的亲电性。一系列亲核芳香族化合物可与MesI（OH）OTs和MesI（OAc）2或由碘异亚丙基生成的原位高价碘（III）物质平稳反应，从而在室温下以高收率提供目标均三甲苯基碘鎓（III）盐具有广泛的功能组耐受性。该C-H冷凝策略优劣高段二芳基碘鎓（III）盐形成过程中具有较高的区域选择性，但在低反应性芳族底物的情况下，主要限制是副产物的形成，这是由于MesI（OH）OTs和MesI（OAc）2中亲核均三甲苯环的自缩合而形成的。

  carbon–heteroatom (C–P, C–O, C–S, and C–N) bonds via C–N cleavage of benzyl ammonium salts under transition-metal-free conditions was reported. The combination of t-BuOK and 18-crown-6 enabled a wide range of substituted benzyl ammonium salts to couple readily with different kinds of heteroatom nucleophiles, i.e. hydrogen phosphoryl compounds, alcohols, thiols, and amines. Good functional group tolerance was demonstrated

  日期：2020.8.21

  The α-lithiobenzyloxy group, easily generated from aryl benzyl ethers by selective α-lithiation with t-BuLi at low temperature, behaves as a directed metalation group (DMG) providing a direct access to o-lithiophenyl α-lithiobenzyl ethers. This ortho-directing effect is reinforced in substrates bearing an additional methoxy group at the meta position. The generated dianions can be reacted with a selection

  α-硫代苄氧基很容易通过在低温下用t -BuLi选择性地进行α-锂化反应而从芳基苄基醚生成，其表现为定向金属化基团（DMG），可直接与邻-硫代苯基α-硫代苄基醚接触。这种邻位导向作用在在间位带有额外甲氧基的底物中得到增强。生成的二价阴离子可与包括羧酸酯和二卤硅烷或锗烷在内的各种亲电试剂反应，这些亲电试剂可从简单的芳基苄基醚制得令人感兴趣的苯并呋喃，硅烷基（锗）二氢苯并呋喃和硅铬烷衍生物。
