用于工业相关氢化反应的高效和选择性纳米结构催化剂的开发继续是化学研究的实际目标。尤其是腈和硝基芳烃的氢化对于伯胺的生产非常重要,伯胺构成了高级化学品,生命科学分子和材料的重要原料和关键中间体。在这里,我们报道了石墨烯壳包封的Co 3 O 4的制备-和钴-纳米颗粒通过碳上对苯二甲酸钴对苯二甲酸MOF的模板合成和随后的热解而负载在碳上。所得的纳米颗粒产生稳定且可重复使用的催化剂,用于官能化和结构多样的芳族,杂环和脂肪族腈以及硝基化合物选择性氢化为伯胺(> 65实例)。这种新型的基于非贵金属的氢化方案的合成和实用性通过将数种反应的规模扩大到数克规模并回收催化剂得到了证明。

The parallel solution-phase synthesis of a new combinatoriallibrary of 3-[4-(R1-coumarin-3-yl)-1,3-thiazol-2-ylcarbamoyl]propanoic acid amides 9 has been developed. The synthesis involves two steps: 1) the synthesis of core building blocks - 3- [4-(coumarin-3-yl)-1,3-thiazol-2-ylcarbamoyl]propanoic acids, 6 - by the reaction of 3-(omega-bromacetyl)coumarins 1 with 3-amino(thioxo)methylcarbamoylpropanoic

or 3-halopropylamine salts with NH-substrates (indoline, 1,2,3,4-tetrahydroquinoline, aniline, and N-ethylaniline) in the presence of NaHCO3 in water furnished various N-aminoalkyl derivatives of heterocyclic and aromatic amines.
A process for the coloration of a substrate, especially a textile, comprising the steps of: (a) applying to the substrate a mixture comprising an aqueous solvent and a water-soluble dye comprising molecules which contain a nucleophilic group and an electrophilic group; and (b) heating or basifying or heating and basifying the dye thereby causing molecules of the dye to join together. Also claimed are dyes, polymers and oligomers.
