  Bisoxazoline-pincer ligated cobalt-catalyzed hydrogenation of alkenes

  摘要：

  The efficient and atom economical hydrogenation of alkenes using a novel bisoxazoline ligated cobalt complex has been developed. The hydrogenation of a variety of alkenes containing electron neutral and electron-donating groups proceeds in high yield, while electron-withdrawing and sterically hindered groups are not tolerated. Heterocycles and internal alkenes were also hydrogenated in moderate to high yields. While the catalyst is enantiopure, no enantioinduction was observed suggesting that other factors are involved in achieving enantiocontrol. (C) 2020 Elsevier Ltd. All rights reserved.

  A substituted phenolic compound is prepared by oxidizing a substituted diarylethane compound with oxygen in the presence of a nitrogen-containing cyclic compound, and treating the oxidized product with an acid. The nitrogen-containing cyclic compound includes, as a constituent of its ring, a skeleton represented by following Formula (I): wherein X is oxygen atom or an -OR group, where R is hydrogen atom or a hydroxyl-protecting group. The substituted diarylethane compound is represented by following Formula (1): wherein each of Ring Ar1 and Ring Ar2 is independently a monocyclic or polycyclic aromatic carbocyclic ring; Y1 is an electron-donating group; Y2 is an electron-withdrawing group; "p" is an integer of 1 or more; and "q" is an integer of 0 or more. The substituted phenolic compound is represented by following Formula (2): wherein Ring Ar1, Y1, and "p" are as defined above.

  The transfer-hydrogenation as well as the regioselective and regiodivergent addition of H−D from regiospecific deuterated dihydroaromatic compounds to a variety of 1,1-di- and trisubstituted alkenes was realised with InBr3 in dichloro(m)ethane. In comparison with the previously reported BF3⋅Et2O-catalysed process, electron-deficient aryl-substituents can be applied reliably and thereby several restrictions

  Simple and efficient procedure for alkylation of aromatics from alcohols in the presence of NaHSO4/SiO2 was developed. Various triaryl methanes were obtained in good yields in short reaction time. For instance the reaction of mesitylene with benzhydrol in the presence of NaHSO4/SiO2 gave the corresponding triaryl methane in a quantitative yield. NaHSO4/SiO2 was regenerated by simple treatment and could

  在NaHSO 4 / SiO 2的存在下，开发了一种简单有效的从醇类将芳烃烷基化的方法。在短的反应时间内以高收率获得了各种三芳基甲烷。例如，在NaHSO 4 / SiO 2的存在下，1，3，5-三甲基苯与苯甲醇的反应以定量收率得到了相应的三芳基甲烷。NaHSO 4 / SiO 2通过简单处理即可再生，可以循环使用八次而不会损失活性。

  conditions. The reaction seems to progress through iron‐catalyzed self‐condensation of the benzyl TMS ether to the corresponding dibenzylic ether. The use of excess arene relative to benzyl TMS ether produced mono‐benzylated arene (di‐ and tri‐arylmethane products), whereas the use of excess benzyl TMS ether versus arene provided bis‐benzylated arene (polyarylated products) in high yields and regioselectivities

  未活化的芳烃和苯甲醇衍生物之间的Friedel-Crafts苄基化反应是清洁且直接的方法，可用于构建对生物有用的二芳基和三芳基甲烷。我们建立了一种在室温下有效的铁催化的Friedel-Crafts苄基化方法，该方法使用苄基TMS醚作为底物，在常见的亲核取代条件下反应性较差。该反应似乎是通过铁催化的苄基TMS醚自缩合为相应的二苄基醚而进行的。相对于苄基TMS醚生产的单苄基化芳烃（二芳基和三芳基甲烷产物）使用过量的芳烃，而相对于芳烃使用过量的苄基TMS醚则可提供高收率和区域选择性的双苄基化芳烃（多芳基化产物）。在以前的方法中，
