  二烷基二芳基甲基醚酸催化歧化反应的合成和机理方面：实验和理论相结合的研究

  摘要：

  各种二烷基二芳基甲基醚的歧化反应是在催化量（10 mol%）的邻苯二磺酰亚胺作为布朗斯台德酸催化剂存在下进行的；反应条件温和，二芳基甲烷目标产物收率良好。催化剂很容易回收和纯化，准备用于进一步的反应。理论研究证实该反应分两步进行：从质子化醚形成碳正离子，然后进行氢化物转移。尽管氢化物转移是决定速率的步骤，但决定反应速率和产率的是碳正离子的稳定性。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2009)

  A surfactant based oxodiperoxo molybdenum complex, which could activate molecular oxygen, has been employed as a catalyst for controlled oxidation of benzylic alcohols to corresponding carbonyls. The oxidation reactions were carried out under aqueous environment, however, in the absence of any extraneous base or co-catalyst. Sensitive/oxidizable functional groups like cyano, sulfide, hydroxyl, aryl-hydroxyl

  基于表面活性剂的氧二过氧钼络合物可以活化分子氧，已被用作催化剂，以控制苄基醇氧化为相应的羰基。氧化反应在水性环境下进行，但是在没有任何无关的碱或助催化剂的情况下进行。在转化过程中可以耐受敏感/可氧化的官能团，例如氰基，硫化物，羟基，芳基-羟基，烯烃（内部/末端），炔烃（内部/末端）和乙缩醛。这种选择性归因于催化剂的温和性质。该方法还可以扩大规模以用于多克合成，并且该方案很可能会得到实际应用，因为它需要廉价的可回收催化剂和易于获得的氧化剂（在绿色条件下）。

  A new concept, “Radiation-Induced Drug (RID)”, was proposed as a novel type of drugs for cancer therapy. To test the usefulness of this concept, 5-fluorouracil (5-FU) derivatives having various types of substituents at the 1-position were prepared and the γ-radiolyses of their aqueous solutions were studied. The compounds having sulfonyl and thioureido groups as the substituents produced efficiently 5-FU with high G values upon γ-irradiation. The medium effects on the radiolyses revealed that the above two substituents were removed mainly with HO· and hydrated electrons eeq−.

• A Metallomicellar Catalyst for Controlled Oxidation of Alcohols and Lignin Mimics in Water using Open Air as Oxidant

  日期：——

  Alcohol groups and β‐O‐4 (C−C) linkages are widespread in biomass feedstock that are abundant renewable resource for value‐added chemicals. The development of sustainable protocols for direct oxidation or oxidative cleavage of feedstock materials in a controlled fashion, using open air as an oxidant is an intellectually stimulating task to produce industrially important value‐added carbonyls. Further, the oxidative depolymerization of lignin into fine chemicals has evoked interest in recent times. Herein, we report the first example of a catalyst system that could activate molecular oxygen from atmospheric air for controlled oxidation and oxidative cleavage/depolymerization of feedstock materials such as alcohols, β‐O‐4 (C−C) linkages and real lignin in water under open air conditions. The selectivity of carbonyl products is controlled by altering the pH between ~7.0 and ~12.0. The current strategy highlights the non‐involvement of any external co‐catalyst, oxidant, radical additives, and/or destructive organic solvents. The catalyst shows a wide substrate scope and eminent functional group tolerance. The upscaled multigram synthesis using an inexpensive catalyst and easily available oxidant evidences the practical utility of the developed protocol. A plausible mechanism has been proposed with the help of a few controlled experiments, and kinetic and computational studies.

  摘要 醇基和 β-O-4 (C-C) 链广泛存在于生物质原料中，它们是丰富的可再生增值化学品资源。利用露天空气作为氧化剂，以可控方式开发原料材料的直接氧化或氧化裂解的可持续方案，是生产具有重要工业价值的羰基化合物的一项具有启发性的任务。此外，将木质素氧化解聚成精细化学品近来也引起了人们的兴趣。在此，我们报告了首个催化剂系统实例，该催化剂系统可激活大气中的分子氧，在露天条件下对醇类、β-O-4（C-C）连接和水中真正的木质素等原料进行受控氧化和氧化裂解/解聚。羰基产物的选择性可通过在 ~7.0 和 ~12.0 之间改变 pH 值来控制。目前的策略突出了不使用任何外部助催化剂、氧化剂、自由基添加剂和/或破坏性有机溶剂的特点。该催化剂具有广泛的底物范围和出色的官能团耐受性。使用廉价的催化剂和易于获得的氧化剂进行多克级合成，证明了所开发方案的实用性。在一些对照实验、动力学和计算研究的帮助下，我们提出了一种合理的机制。
