The applicability of the optimal catalyst material is shown by hydrogenation of >110 diverse aliphatic and aromatic nitriles including functionalized and industrially relevant substrates. Challenging heterocyclic nitriles, specifically cyanopyridines, provided the corresponding primary amines in good to excellent yields. The resulting amines serve as important precursors and intermediates for the preparation
二氧化硅负载的超小 Ni 纳米颗粒允许在温和条件下将各种腈类普遍和选择性地氢化为伯胺。通过煅烧由 Ni( II ) 生成的模板材料)硝酸盐和胶体二氧化硅在空气下,随后在分子氢存在下还原,制备最佳催化剂。制备的负载型纳米颗粒稳定,使用方便,易于回收利用。最佳催化剂材料的适用性通过对超过 110 种不同的脂肪族和芳香族腈(包括功能化和工业相关底物)进行氢化来证明。具有挑战性的杂环腈,特别是氰基吡啶,以良好的收率提供了相应的伯胺。所得胺可作为制备众多生命科学产品和聚合物的重要前体和中间体。
