Imine to secondary amine
Witryna2 lut 2024 · The pH for reactions which form imine compounds must be carefully controlled. The rate at which these imine compounds are formed is generally greatest … Witryna1 kwi 2024 · The yield of the secondary amine ( ) dramatically increased to a remarkably high yield of 80% at only 6 h. The control of the reaction time in mesitylene can allow an efficient one-pot synthesis of the imine and secondary amine. Notably, the yield of the secondary amine ( ) was slightly lower than that of the parent imine ( ).

Witryna14 lis 2014 · A possible overall mechanistic scheme for the formation of secondary amines from primary alcohols and ammonia is as follows (Scheme 2): 1) formation of the primary amine via borrowing hydrogen strategy [29, 47]; an intermediate aldehyde formed by dehydrogenation of the alcohol reacts with ammonia to form an imine a … Witrynaimine.11 Previously established aminating enzyme platforms such as transaminases, amine dehydrogenases, and ammonia lyases are largely limited to the production of primary amines, with a few examples of the formation of secondary amines.12−14 In contrast, reductive amination with IREDs enabled the direct synthesis of primary, …
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 … Witryna29 lip 2024 · Herein, we report the first example of efficient reductive amination of ketones/aldehydes with amines using BH 3 N(C 2 H 5) 3 as a catalyst and a reductant under mild conditions, affording various tertiary and secondary amines in excellent yields. A mechanistic study indicates that BH 3 N(C 2 H 5) 3 plays a dual function role …
