Colloidal and Nanosized Catalysts in Organic Synthesis: XX. Continuous Hydrogenation of Imines and Enamines Catalyzed by Nickel Nanoparticles
摘要:
Nickel nanoparticles on the BAU-A active carbon or NaX zeolite catalyze hydrogenation of imines and enamines in a flow reactor in a gas phase or in a gas-liquid-solid catalyst system. The process occurs at atmospheric pressure of hydrogen and gives secondary or tertiary amines in a high yield.

One-pot tandem synthesis was developed for substituted quinolines (in up to 97% yields) involving a selective catalytic oxidation of primary amines to aldehydes and their condensation with arylamines under the action of a dispersion of Fe(CrO2)2 and water solution of H2O2 at room temperature. The stage of catalytic oxidation of alcohols was accelerated by photoactivation. A presumable mechanism of
开发了一锅串联合成的取代喹啉(产率高达97%),涉及在Fe(CrO 2)2和水的水溶液的分散作用下,伯胺选择性催化氧化为醛,并与芳胺缩合。室温下为H 2 O 2。通过光活化加速了醇的催化氧化阶段。提出了一种光活化串联合成2-甲基喹啉的推测机理。通过光化学合成制备催化剂Fe(CrO 2)2。
