  GaN纳米线作为可重复使用的光氧化还原催化剂，用于黑光照射下羰基的自由基偶联

  摘要：

  长期以来，利用光能驱动所需的化学转化。自由基偶联反应中均相光氧化还原催化剂的开发确实是惊人的，但是具有明显的缺点，例如难以分离催化剂和经常需要稀有贵金属。因此，我们设想使用具有可调费米能级和能带的超稳定III-V光敏半导体作为自由基耦合反应的易于隔离和可回收的异质光氧化还原催化剂。在本文中，使用羰基偶联反应作为概念验证，我们报道了在室温下，环境光下，以甲醇为溶剂和牺牲试剂，GaN纳米线催化的光频哪醇偶联反应。通过简单地调整掺杂剂，GaN纳米线显示出​​显着增强的电子性能。该催化剂表现出优异的稳定性，可重复使用性和功能耐受性。所有反应都可以在Si晶圆上用单条纳米线完成。

• CBZ6 as a Recyclable Organic Photoreductant for Pinacol Coupling
  作者：Hua Wang、Jian-Ping Qu、Yan-Biao Kang

  日期：2021.4.16

  % CBZ6)-catalyzed reductive (pinacol) coupling of aldehydes, ketones, and imines has been developed. Irradiated by purple light (407 nm) using triethylamine as an electron donor, a variety of 1,2-diols and 1,2-diamines could be prepared. The oxidation potential of the excited state of CBZ6 is established as −1.92 V (vs saturated calomel electrode (SCE)). The relative high reductive potential enables

  已经开发了可回收的有机光还原剂（1摩尔％CBZ6）催化的醛，酮和亚胺的还原（频哪醇）偶联。使用三乙胺作为电子供体，在紫色光（407 nm）照射下，可以制备各种1,2-二醇和1,2-二胺。CBZ6的激发态的氧化电位为-1.92 V（相对于饱和甘汞电极（SCE））。较高的还原电位使得羰基化合物及其衍生物能够还原偶联。CBZ6可以克量制备，并且对酸/碱或空气稳定。可用于大规模光还原合成，反应后高收率回收。

  105 for the reduction to alcohol and pinacol formation, respectively, and are very stable so that they can be recycled for at least 10 times in the reactions without significant loss of catalytic activity. The additional advantages of this method include good functional group tolerance, mild reaction conditions, the allowance of selectively reducing aldehydes in the presence of ketones, and easiness

  我们提出了一种有效且通用的可见光驱动方法，以CdSe / CdS核/壳量子点作为光催化剂将芳基醛和酮化学选择性地转化为醇或频哪醇产品。在这些反应中，硫酚被用作质子和氢原子的供体，以及被激发的量子点（QD）的空穴陷阱。只需更改反应系统中的硫酚含量，即可将两种产物从一种转换为另一种。核/壳QD催化剂高效，周转数（TON）大于4×10 4和4×10 5分别还原成醇和频哪醇形成，并且非常稳定，因此它们可以在反应中循环至少10次，而不会明显降低催化活性。该方法的其他优点包括良好的官能团耐受性，温和的反应条件，允许在存在酮的情况下选择性还原醛以及易于大规模反应。通过猝灭实验和自由基捕获实验研究了反应机理，并给出了随着反应条件的变化反应路径发生切换的原因。

  日期：——

  Efficient carbon–carbon bond formation is of great importance in modern organic synthetic chemistry. The pinacol coupling discovered over a century ago is still one of the most efficient coupling reactions to build the C–C bond in one step. However, traditional pinacol coupling often requires over-stoichiometric amounts of active metals as reductants, causing long-lasting metal waste issues and sustainability

  高效的碳-碳键形成在现代有机合成化学中非常重要。一个多世纪前发现的频哪醇偶联仍然是一步构建 C-C 键的最有效偶联反应之一。然而，传统频哪醇偶联通常需要过量化学计量的活性金属作为还原剂，从而导致长期存在的金属废料问题和可持续性问题。一个巨大的科学挑战是设计一种无金属的频哪醇偶联反应方法。在这里，我们描述了一种光驱动频哪醇耦合协议，不使用任何金属，但使用 N 2 H 4，用作清洁的非金属氢原子转移 (HAT) 还原剂。在这种转化中，只有无痕无毒的N 2和H 2气体作为副产物产生，具有相对广泛的芳香酮范围和良好的官能团耐受性。对该机制的实验和计算研究表明，这种新颖的频哪醇偶联反应是通过光激发酮和 N 2 H 4之间的 HAT 过程进行的，而不是金属还原剂的常见单电子转移 (SET) 过程。

• Novel Reduction of Carbonyl Compounds with Al/NH₃/Halide under Irradiation of Ultrasonic Wave
  作者：Ryu Sato、Takeshi Nagaoka、Takehiko Goto、Minoru Saito

  DOI：10.1246/bcsj.63.290

  日期：1990.1

  Various carbonyl compounds, such as benzophenones and acetophenones, were reduced by Al/NH3/halide under ultrasonic wave irradiation to give the corresponding monohydric alcohols and/or pinacols in satisfactory yields. The addition of inorganic halides improved the selectivity in the formation of monohydric alcohols and pinacols.
