在此,我们报道了通过二氧化硅上钴均苯四酸的模板合成和随后的热解制备的特定二氧化硅负载的Co/Co 3 O 4核壳纳米粒子的合成。最佳的催化剂材料允许在相对温和的反应条件下对吡啶、喹啉和其他杂芳烃(包括吖啶、菲咯啉、萘啶、喹喔啉、咪唑并[1,2-a]吡啶和吲哚)进行全面和选择性氢化。此外,还展示了这些钴纳米颗粒的回收利用及其脱氢催化能力。
Monoamine Oxidase (MAO-N) Whole Cell Biocatalyzed Aromatization of 1,2,5,6-Tetrahydropyridines into Pyridines
摘要:
A sustainable MAO-N biocatalyzed process for the synthesis of pyridines from aliphatic tetrahydropyridines (THP) has been developed. Pyridine compounds were synthesized under mild reaction conditions and with high conversion, exploiting MAO-N whole cells as aromatizing biocatalysts. The kinetic profile of the whole cell biocatalytic transformation was finally investigated via in situ F-19 NMR.

also the fine‐tuning of physicochemical and biological properties of drugs, agrochemicals and polymers. We report here a general and practical photochemical strategy enabling the site‐selective chlorination of sp3 C−H bonds. This process exploits the ability of protonated N‐chloroamines to serve as aminium radical precursors and also radical chlorinatingagents. Upon photochemical initiation, an efficient
