Imine to secondary amine
WitrynaHeteroaromatic amine 9 was found to provide the desired imine 10 in 85% yield in 90 min. To achieve the imine as the major product this reaction was conducted in refluxing acetonitrile, as lower temperatures resulted in a mixture of triazane species. Heterocyclic compounds 11 and 13 achieved >99% conversion within 20 min.

WitrynaReaction with primary amines to form imines. The reaction of aldehydes and ketones with ammonia or 1º-amines forms imine derivatives, also known as Schiff bases (compounds having a C=N function). Water is eliminated in the reaction, which is acid-catalyzed and reversible in the same sense as acetal formation. Witryna13 kwi 2024 · In addition, the amide group of the products could be replaced through transamidation of 1 or 30 with alkyl amine (to give 107), amino acid l-Tyr(t Bu)-O t Bu (to give 109) and amine drugs such as ...
WitrynaSolvothermal synthesized CeO2 nanoflakes were plasma treated under different atmospheres (combination of Ar, H2, O2 and NH3), and further used for imine synthesis. The plasma processing can improve the amount of surface oxygen vacancies, Ce3+ ratio, and the peroxy anions O22− ratio. All the three parameters can influence the … WitrynaProvided is a process for converting an amide into an amine comprising hydrogenation of the amide at a temperature not higher than 130°C and a hydrogen pressure not higher than 50 bar in the presence of a supported heterogeneous catalyst preparable by a method comprising depositing vanadium on a supported noble metal catalyst by …
