  CNN-钌配合物催化酯加氢

  摘要：

  Ruthenium complexes supported by two new CNN-pincer ligands were synthesized. Both were tested as catalysts for the hydrogenation of esters under mild conditions (105 degrees C, 6 bar H-2). A striking dependence on ligand structure was observed, as a dimethylamino-substituted ligand gave a nearly inactive catalyst, while a diethylamino-substituted variant gave up to 980 catalytic turnovers for the hydrogenation of benzyl benzoate. This system catalyzes the hydrogenation of various substrates including ethyl, benzyl, and hexyl esters, but is surprisingly unreactive toward methyl esters. Experiments demonstrate that base-catalyzed transesterification is rapid under the reaction conditions and that methyl esters are effectively hydrogenated when benzyl alcohol is added to the reaction mixture. The reverse reaction, dehydrogenation of primary alcohols to give esters, was tested as well; up to 920 catalytic turnovers were observed for the dehydrogenation of 1-hexanol to hexyl hexanoate.

  be a highly efficient and reusable solid catalyst for the esterification of various carboxylic acids with a variety of alcohols to furnish corresponding esters in high to excellent yields. The catalytic activity of the GrO5000 was attributed to the ability of highly polar GrO5000 scaffold to adsorb/attract reactants, where the acid functionalities of GrO5000 facilitated the esterification process efficiently

  根据Hummers方法制备的氧化石墨烯（GrO），根据其在水中的分散稳定性，分为三个不同的部分（GrO 5000，GrO 2000和GrO res）。红外，核磁共振，X射线光电子能谱和元素分析表明，与其他组分相比，GrO 5000具有较高的氧官能度，包括酚，羧基和-OSO 2 H基团。发现GrO 5000是一种高效且可重复使用的固体催化剂，用于将各种羧酸与各种醇进行酯化反应，从而以高至极好的收率提供相应的酯。GrO的催化活性5000归因于高极性GrO 5000支架吸附/吸引反应物的能力，其中GrO 5000的酸官能度有效地促进了酯化过程。讨论了GrO 5000的化学和结构特征，以了解与GrO 2000和常规固体酸催化剂相比催化活性的提高。版权所有©2014 John Wiley＆Sons，Ltd.

  Processes are disclosed for preparing carboxylic acids from organic esters, the processes comprising contacting an ester with water in the presence of an acid catalyst and a homogenizing solvent at conditions effective to form a carboxylic acid. The homogenizing solvent is present in an amount sufficient to form a single-phase reaction mixture comprising the ester, water, and homogenizing solvent. The homogenizing solvent may be selected from acetonitrile, dimethyl sulfoxide, and 1,4-dioxane.

  alcohols catalyzed by mesoporous metal oxides (manganese and cobalt oxides) is reported under base and solvent free conditions. For a range of aliphatic alcohols, up to 90 % conversions to esters was achieved. The catalytic reaction is likewise applicable to neat aldehydes as substrates with yields of up to 86 %. High pressure batch reaction for ethanol to ethyl acetate led to 22 % yield. Isotope labeling
