  摘要：

  AbstractA one‐pot transformation of aldehydes into α,β‐unsaturated aldehydes was developed using both N‐benzyl‐N‐methylamine and 2,3‐dichloro‐5,6‐dicyano‐1,4‐benzoquinone (DDQ) as catalysts and MnO2 as a terminal oxidant. An oxidative and enantioselective reaction of aldehydes and nitromethane was established using both diphenylprolinol silyl ether and DDQ as a catalyst with MnO2 as a terminal oxidant, in which synthetically important β‐substituted γ‐nitro aldehydes were obtained with excellent enantioselectivity.magnified image

  selective hydrogenation and deuteration of a variety of alkenes is presented. Key to success for these reactions is the use of a specific nickel-graphitic shell-based core–shell-structured catalyst, which is conveniently prepared by impregnation and subsequent calcination of nickel nitrate on carbon at 450 °C under argon. Applying this nanostructured catalyst, both terminal and internal alkenes, which

  提出了各种烯烃的选择性氢化和氘化的通用方案。这些反应成功的关键是使用特定的镍-石墨壳基核壳结构催化剂，该催化剂可以通过浸渍碳上的硝酸镍并随后在氩气下于 450 °C 下煅烧来方便地制备。应用这种纳米结构催化剂，具有工业和商业重要性的末端烯烃和内部烯烃在环境条件下（室温，使用1巴氢气或1巴氘）进行选择性氢化和氘化，从而获得相应的烷烃和氘。标记烷烃的收率良好至极好。通过克级反应以及高效的催化剂回收实验证明了这种镍基加氢方案的合成效用和实用性。

  Bad odors on textile materials are often caused by body odor. The invention relates to a textile material treatment method for inhibiting body odor on textile materials, by which means the treated textiles, after having been worn, even after sweat-inducing sports activities, have a significantly reduced bad odor or even no odor. The invention also relates to a perfume composition and to a textile material treatment agent, respectively comprising urea derivatives and/or phenacylthiazolium salts, that counteract the formation of body odor.
